SLVUD19B August 2024 – April 2025 TPSI31P1-Q1
The TPSI31P1-Q1 device is an isolated gate driver with integrated comparators intended for hysteretic current control in charging a DC-link capacitor. When enable (EN) goes high, the driver (VDRV) turns on until the voltage across the comparator (IS+) exceeds 1.2V. Once IS+ exceeds 1.2V, VDRV turns off until IS+ falls below 160mV. Once IS+ falls below 160mV, VDRV turns on, and this cycle repeats until the DC-link capacitor is fully charged.
