TD62S312AFM
1-Channel Darlington Source-Current Driver
TD62S312AFM is a 1-channel noninverting source-current driver.
The driver incorporates output clamp diodes used to clamp the
counter electromotive force which is generated when driving an
inductive load, and an input resistor which limits base current.
The driver is optimal for driving relays and LEDs. When using
the driver, pay attention to the thermal conditions.
Features
• Ultra-small HSON6 package with heat sink on rear
• Large output voltage: VOUT = −50 V (min)
• Large output current: IOUT = −100 mA (max)
• Built-in input resistor: RIN = 10 kΩ
• Input signal: High Level Active
• Built-in output clamp diodes
Pin Connection (t op view) Basic Circuit Diagram
Note 1: Diodes shown using dotted lines are parasitic. Do not use them.
Note 2: W hen using the driver, connect the OUTPUT pin to the TEST pin.
Note 3: When using the driver, connect the P-GND pin to the heat sink on the rear of the package.

Caution on Application
1. The device does not include protectors such as an overcurrent protector and an overvoltage protector.
Applying excessive current or voltage may damage the device.
Thus, design with great care to prevent excessive current or voltage from being applied to the device.
The device may also be damaged by short-circuits between outputs and power supply/ground.
Take care when designing output, VCC and GND line.
2. Be sure to mount the device in the correct orientation. Make sure that the positive and negative
power supply pins are connected the right way round. Otherwise, the absolute maximum current
and power dissipation ratings may be exceeded and the device may break down or undergo
performance degradation, causing it to catch fire or explode, and resulting in injury.
