IR3316(S)PbF
LOW EMI CURRENT SENSE HIGH SIDE SWITCH
Features
Load current feedback
Programmable over current shutdown
Active clamp
ESD protection
Input referenced to Vcc
Over temperature shutdown
Switching time optimized for low EMI
Reverse battery protection
Description
The IR3316(S)PbF is a fully protected 4 terminals high
side switch. The input signal is referenced to Vcc. When
the input voltage Vcc - Vin is higher than the specified
threshold, the output power Mosfet is turned on. When the
Vcc - Vin is lower than the specified Vil threshold, the
output Mosfet is turned off. A current proportional to the
power Mosfet current is sourced to the Ifb pin. Over
current shutdown occurs when Vst-Vin > 4.5V. The current
shutdown threshold is adjusted by selecting the proper
RIfb. Either over current and over temperature latches off
the switch. The device is reset by pulling the input pin
high. Other integrated protections (ESD, reverse battery,
active clamp) make the switch very rugged in automotive
environment.

(4) Input thresholds are measured directly between the input pin and the tab. Any parasitic resistance in common between
the load current path and the input signal path can significantly affect the thresholds.
(5) Rdson is measured between the tab and the Out pin, 5mm away from the package.
