SLVSAX6C – OCTOBER 2011 – REVISED JUNE 2012

OVERTEMPERATURE PROTECTION

The TPS20xxC dual includes per channel overtemperature protection circuitry, which activates at 135°C (min)

junction temperature while in current limit. There is an overall thermal shutdown of 155°C (min) junction

temperature when the TPS20xxC dual is not in current limit. The device remains off until the junction temperature

cools 20°C and then restarts. Thermal shutdown may occur during an overload due to the relatively large power

fault is removed. This topology allows one channel to continue normal operation even if the other channel is in an

over-temperature condition.

SOFTSTART, REVERSE BLOCKING AND DISCHARGE OUTPUT

The power MOSFET driver incorporates circuitry that controls the rise and fall times of the output voltage to limit

large current and voltage surges on the input supply, and provides built-in soft-start functionality.

The TPS20xxC dual power switch will block current from OUT to IN when turned off by the UVLO or disabled.

The TPS20xxC dual includes an output discharge function on each channel. A 470

Ω (typ.) discharge resistor will

dissipate stored charge and leakage current on OUTx when the device is in UVLO or disabled. However as this

circuit is biased from IN, the output discharge will not be active when IN voltage is close to 0 V.
