Inhibit function
The inhibit feature is used to put the device in standby mode. With the INH pin higher than
2.2 V, the device is disabled and the power consumption is reduced to less than 100 µA.
With the INH pin lower than 0.8 V, the device is enabled. If the INH pin is left floating, an
internal pull-up ensures that the voltage at the pin reaches the inhibit threshold and the
device is disabled. The pin is also V
Thermal shutdown
The shutdown block generates a signal that turns off the power stage if the temperature of
the chip goes higher than a fixed internal threshold (150±10 °C). The sensing element of the
chip is very close to the PDMOS area, ensuring fast and accurate temperature detection. A
hysteresis of approximately 20 °C keeps the device from turning on and off continuously.
