ZHCSPA4 march 2023 TPS548C26
PRODUCTION DATA
The TPS548C26 device actively monitors the PVIN input voltage. When the PVIN voltage level is above the input overvoltage threshold, TPS548C26 device stops switching and pulls PG signal low. The PVIN OV rising threshold is typically 18.6 V while the PVIN OV falling threshold is typically 13.4 V.
After the PVIN overvoltage fault is triggered, the device latches off both the high-side and low-side FETs until the EN pin is toggled or PVIN is reset.
