ASSEMBLY TEST PROCEDURE
A power supply set to 3.6 V and current limit set to at least
1.5 A must be connected to J15 connector to powering the
NCP2823 Series evaluation board. Also to compensate for
parasitic inductance of wires between the power supply and
the evaluation board it is highly recommended to connect a
470 mF electrolytic capacitor to bypass J11 terminal. Like
this the device can be evaluate under powering condition
very similar that battery power supplies.
These tests are provided in order to guarantee a good
assembly of the NCP2823 on its dedicated board, it do not
consist in parametric test which is already done at chip level.
SHUTDOWN TEST
Switches setup for shutdown test:
Symbol Switch Description
J1 Must be connected to ground (low side)
*All other switches must be kept floating
Tests:
1. Set the switches in the configuration
2. Power the board with a 3.6 V power supply
limited at 1.5A and bypassed by a 470 mF
electrolytic capacitor.
3. Measure the current on the power supply (must be
inferior to 1 mA)
Wake up test
Switches setup for wire mode test:
Symbol Switch Description
J1 Must be connected to VDD (high side)
*All other switches must be kept floating
Tests:
4. Set the switches in the configuration
5. Power the board with a 3.6 V power supply
limited at 1.5 A and bypassed by a 470 mF
electrolytic capacitor.
6. Measure DC Output voltage on J12 on J13 and
GND. DC Voltage must be equal to 1.8 V
7. Measure DC input voltage on J5−2 on J6−2 and
GND. DC Voltage must be equal to 1.26 V
