Absolute Maximum Ratings

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters

are referenced to Vcc lead. (TAmbient = 25

1) Limited by junction temperature. Pulsed current is also limited by wiring

2) <500 Ohm or shorting Ifb to gnd may damage the part with Isd around 120A

3) >5000 Ohm or leaving Ifb open will shutdown the part. No current will flow in the load.
