SINGLE/DUAL CHANNEL INTELLIGENT POWER SIDE SWITCH
Over temperature shutdown Over current shutdown Active clamp current logic level input protection Optimized Turn On/Off Diagnostic input current
Product Summary Rds(on) 250m (max.) Vclamp Ishutdown 2.8A (typ.) Packages
Description
IPS1051LPbF IPS1052GPbF Intelligent Power Switches (IPS) featuring side MOSFETs with over-current, over-temperature, protection drain source active clamp. IPS1052G dual channel device while IPS1051 single channel. These devices offer protections high reliability required harsh environments. Each switch provides efficient protection turning power MOSFET when temperature exceeds 165°C when drain current reaches device restarts once input cycled. serial resistance connected input provides diagnostic. avalanche capability significantly enhanced active clamp covers most inductive load demagnetizations.
