Frequently Asked Questions
What is the nominal load current (I_L) rating?
The Nominal load current (I_L) is specified as 1.6 A.
How does the TOPFET manage potential power surges?
It includes Overload protection, which limits the output current and activates upon detection of a short circuit. It also features ESD protection on all pins.
Is this device compatible with different voltage levels?
The continuous off-state supply voltage ranges from 0 V up to 50 V. It supports low logic compatible input (5 V).
What is the maximum operating temperature range?
The continuous junction temperature (T_j) can reach 150 °C, and the storage temperature range is -55 °C to 175 °C.
