To our customers,

Old Company Name in Catalogs and Other Documents

On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology

Corporation, and Renesas Electronics Corporation took over all the business of both

companies. Therefore, although the old company name remains in this document, it is a valid

Renesas Electronics document. We appreciate your understanding.

The high-side output is turned on, if the input pin is shorted to ground. The input current is below IIH. The high-side

output is turned off, if the input pin is open or the input current is below IIL. Rin0 is 130 Ω typ. ESD protection diode:

Switching an inductive load

Dynamic clamp operation at inductive load switch off

The dynamic clamp circuit works only when the inductive load is switched off. When the inductive load is switched off,

the voltage of OUT falls below 0 V. The gate voltage of SW1 is then nearly equal to GND because the IS terminal is

connected to GND via an external resister. Next, the voltage at the source of SW1 (= gate of output MOS) falls below

the GND voltage. SW1 is turned on, and the clamp diode is connected to the gate of the output MOS, activating the

dynamic clamp circuit.

When the over-voltage is applied to VCC, the gate voltage and source voltage of SW1 are both nearly equal to GND.

SW1 is not turned on, the clamp diode is not connected to the gate of the output MOS, and the dynamic clamp circuit is

not activated.

Over-temperature protection

The output is switched off if over-temperature is detected. The device switches on again after it cools down.

Power dissipation under reverse battery condition

In the case of a reverse battery condition, the intrinsic body diode causes power dissipation. Additional power is

dissipated by the internal resister. The following is the formula for estimation of total power dissipation Pd(rev) in a

reverse battery condition.

Pd(rev) = Vds(rev) x IL + (VCC – Vf – Iin(rev) x Rin) x Iin(rev) + (VCC − Iis(rev) x Ris) x Iis(rev)

Iin(rev) = (VCC − ( Vf +Vf,IN)) / (Rin0 + Rin)

Iis(rev) = (VCC − Vf,IS) / (Ris0 + Ris)

Vf,IN: Forward voltage of Vz,IN

Vf,IS: Forward voltage of Vz,IS

Vf: Forward voltage of parasitic diode of external input switch

The reverse current through the intrinsic body diode has to be limited by the connected load. The current through

sense pin IN is limited by Rin0 130 Ω typ.. (Please refer to Current sense output). The current through input pin IS is

limited by Ris0 130 Ω typ. and external Ris. (Please refer to Driver Circuit (On-Off Control)).

Data Sheet S18529EJ3V0DS00 13

PD166007

Device behavior at low voltage condition

If the voltage supply goes down, the device cannot keep a fully ON state under 4.6 V(typ.), and Von voltage is going

to increase. Then, if Von voltage goes over Von(OvL), the device shuts down the output. Shutdown is latched until the

next reset via input. Shutdown does not work during td(oc) after input is active. VON(OvL) goes down under 4.6 V.

Application example in principle

1) In order to prevent leakage current through at IN terminal via PCB,

it is recommended to pull up the IN terminal to VCC using around 1 to10 kΩ (approx.) resistor.

2) If output current is over destruction current characteristics for inductive load at a single off,

it must be connected through an external component for protection purpose.

3) If current sense and diagnostic features are not used, IS terminal has to be connected to GND via resistor.

VOLTAGE APPLICATION WAVEFORM AT INPUT PIN

Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the

CMOS device stays in the area between V

(MAX) and V

(MIN) due to noise, etc., the device may

malfunction. Take care to prevent chattering noise from entering the device when the input level is fixed,

and also in the transition period when the input level passes through the area between V

(MAX) and

(MIN).

HANDLING OF UNUSED INPUT PINS

Unconnected CMOS device inputs can be cause of malfunction. If an input pin is unconnected, it is

possible that an internal input level may be generated due to noise, etc., causing malfunction. CMOS

devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed

high or low by using pull-up or pull-down circuitry. Each unused pin should be connected to V

or GND

via a resistor if there is a possibility that it will be an output pin. All handling related to unused pins must

be judged separately for each device and according to related specifications governing the device.

PRECAUTION AGAINST ESD

A strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and

ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as

much as possible, and quickly dissipate it when it has occurred. Environmental control must be

adequate. When it is dry, a humidifier should be used. It is recommended to avoid using insulators that

easily build up static electricity. Semiconductor devices must be stored and transported in an anti-static

container, static shielding bag or conductive material. All test and measurement tools including work

benches and floors should be grounded. The operator should be grounded using a wrist strap.

Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for

PW boards with mounted semiconductor devices.

STATUS BEFORE INITIALIZATION

Power-on does not necessarily define the initial status of a MOS device. Immediately after the power

source is turned ON, devices with reset functions have not yet been initialized. Hence, power-on does

not guarantee output pin levels, I/O settings or contents of registers. A device is not initialized until the

reset signal is received. A reset operation must be executed immediately after power-on for devices

with reset functions.

POWER ON/OFF SEQUENCE

In the case of a device that uses different power supplies for the internal operation and external

interface, as a rule, switch on the external power supply after switching on the internal power supply.

When switching the power supply off, as a rule, switch off the external power supply and then the

internal power supply. Use of the reverse power on/off sequences may result in the application of an

overvoltage to the internal elements of the device, causing malfunction and degradation of internal

elements due to the passage of an abnormal current.

The correct power on/off sequence must be judged separately for each device and according to related

specifications governing the device.

INPUT OF SIGNAL DURING POWER OFF STATE

Do not input signals or an I/O pull-up power supply while the device is not powered. The current

injection that results from input of such a signal or I/O pull-up power supply may cause malfunction and

the abnormal current that passes in the device at this time may cause degradation of internal elements.

Input of signals during the power off state must be judged separately for each device and according to

related specifications governing the device.

NEC Electronics products are classified into the following three quality grades: "Standard", "Special" and

"Specific".

The "Specific" quality grade applies only to NEC Electronics products developed based on a customer-

designated "quality assurance program" for a specific application. The recommended applications of an NEC

Electronics product depend on its quality grade, as indicated below. Customers must check the quality grade of

each NEC Electronics product before using it in a particular application.

The quality grade of NEC Electronics products is "Standard" unless otherwise expressly specified in NEC

Electronics data sheets or data books, etc. If customers wish to use NEC Electronics products in applications

not intended by NEC Electronics, they must contact an NEC Electronics sales representative in advance to

determine NEC Electronics' willingness to support a given application.
