IR3314(S)PbF
PROGRAMMABLE CURRENT SENSE HIGH SIDE SWITCH
Features
• Load current feedback
• Programmable over current shutdown
• Active clamp
• ESD protection
• Input referenced to Vcc
• Over temperature shutdown
• Reverse battery protection
• Lead-Free
Description
The IR3314(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.
