ZHCSHZ6A April 2018 – December 2018 TPS746
PRODUCTION DATA.
The TPS746 uses an undervoltage lockout (UVLO) circuit that disables the output until the input voltage is greater than the rising UVLO voltage (VUVLO). This circuit ensures that the device does not exhibit any unpredictable behavior when the supply voltage is lower than the operational range of the internal circuitry. When VIN is less than VUVLO, the output is connected to ground with a pulldown resistor (RPULLDOWN).
