IR6226 preliminary data sheet 6.051 intelligent high side mosfet power switch general description: the IR6226 is a 5 terminal monolithic high side switch with built in short circuit, over- temperature, esd, inductive load turn off capability and diagnostic feedback. the on-chip protection circuit goes into pwm mode, limiting the average current during short circuit if the drain current exceeds 5a. the protection circuit latches off the high side switch if the junction temperature exceeds 170c and latches on after the junc- tion temperature falls by 10c. the drain to source voltage is actively clamped at 55v, improving its performance during turn off with inductive loads. the on-chip charge pump high side driver stage is floating and ref- erenced to the source of the power mosfet. thus the logic to power ground isolation can be as high as 50v. this allows opera- tion with larger offset as well as controlling the switch during load energy recirculation or regeneration. a diagnostic pin is provided for status feedback of short circuit, over temperature and open load detection. applications ? solenoid driver ? dc motor driver v cc (op) 5v-50v r ds(on) 100m w i lim 20a t j(sd) 170c e av 200mj condition in out dg normal h h h normal l l l output open h h h output open l h h shorted output h current-limiting l shorted output l l l over-temperature h l l over-temperature l l l truth table available packages block diagram IR6226 to-220 (5-lead) features pwm current limit for short circuit protection over-temperature protection active output negative clamp reverse battery protection broken ground protection short to v cc protection low noise charge pump sleep mode supply current 4kv esd protection on all pins logic ground isolated from power ground
