Hi Matisse,
There is a tBLANK time, typically 100 µs, between the SNS voltage exceeding VIH,SNS and PG being asserted high. Since this device's PG is dependent on EN exceeding VIH,EN and the voltage on SNS exceeding VIH,SNS, the delay from EN…
Hi ACGUY,
The TPS22953 will reach to a short to gnd in 5us (Tdeglitch). Depending on the severity of the output short to gnd, it could exceed the absolute maximum of the device within this period of time. The severity of the short is system dependent…
