AUIPS2051L

March, 23rd 2009 Automotive grade AUIPS2051L/AUIPS2052G INTELLIGENT POWER LOW SIDE SWITCH Features • • • • • • • Over temperature shutdown Over current shutdown Active clamp Low current & logic level input ESD protection Optimized Turn On/Off for EMI Diagnostic on the input current Product Summary Rds(on) 300mΩ (max.) Vclamp 70V Ishutdown 1.8A (typ.) Packages Description The AUIPS2051L/AUIPS2052G is a three terminal Intelligent Power Switch (IPS) that features a low side MOSFET with over-current, over-temperature, ESD protection and drain to source active clamp. The AUIPS2052 is a dual channel device while the AUIPS2051 is a single channel.This device offers protections and the high reliability required in harsh environments. The switch provides efficient protection by turning OFF the power MOSFET when the temperature exceeds 165°C or when the drain current reaches 1.8A. The device restarts once the input is cycled. A serial resistance connected to the input provides the diagnostic. The avalanche capability is significantly enhanced by the active clamp and covers most inductive load demagnetizations.
