Frequently Asked Questions
What protection mechanisms are included in this TOPFET high side switch?
It includes overtemperature protection, load current limiting, latched overload/short circuit protection, and detection for open-circuit loads.
What is the continuous junction temperature limit for operation?
The maximum continuous junction temperature (Tj) is 150 °C.
How does the device perform when handling inductive loads during turn-off?
During turn-off, the load pin voltage goes negative with respect to ground. The non-repetitive clamping energy limit must be observed (-150 mJ).
What is the on-state resistance (R_on) at standard operating conditions?
At 25°C, under a 10A load for 300 µs, the typical R_on on a general controller is 38 mΩ.
