1µs. Once the e-fuse turns off, the part starts up

after a delay (200ms). If the short still remains,

then VGATE is regulated to maintain the current

at its ILIMIIT level, and the part enters hiccup

mode after a 200ms off time (tOFF). The MP5098

repeats this operation until the short circuit has

been removed.

Enable

EN is a digital control pin that enables and

disabled the current-limit MOSFET. Pull EN low

or float EN to turn the current-limit MOSFET on;

pull EN high to turn it off. An internal 770kΩ

resistor connected between EN and GND

allows EN to float to start up the device.

Thermal Shutdown

Thermal shutdown monitors the silicon die

temperature to prevent the chip from operating

at

exceedingly

high

temperatures.

If

the

temperature exceeds 155°C, then the part

shuts down.
