ZHCSLY5A August 2020 – July 2021 TPS65994AD
PRODUCTION DATA
The VIN_3V3 input is the main supply of the TPS65994AD device. The VIN_3V3 switch (see Power Management) is a uni-directional switch from VIN_3V3 to LDO_3V3, not allowing current to flow backwards from LDO_3V3 to VIN_3V3. This switch is on when the 3.3 V supply is availableand the dead-battery flag is cleared. The recommended capacitance CVIN_3V3 (see the Recommended Capacitance in the Specifications section) should be connected from the VIN_3V3 pin to the GND pin.
