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
o
C unless otherwise specified).
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 90A
3) >5000 Ohm or leaving Ifb open will shutdown the part. No current will flow in the load.
