  IR6224 (note: for new designs, we recommend ir?s new products ips521 and ips521s) data sheet 60050 - h intelligent high side mosfet power switch features ? pwm current limit for short circuit protection ? over-temperature protection ? active output negative clamp ? reverse battery protection for logic circuit ? broken ground protection ? short to v cc protection ? low noise charge pump ? sleep mode supply current ? 4kv esd protection on all leads ? logic ground isolated from power ground general description the IR6224 is a 5 terminal monolithic high side switch with built in short circuit, over- temperature, esd protections, induc- tive 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 20a. the protection circuit latches off the high side switch if the junction temperature exceeds 170 o c and latches on after the junction temperature falls by 10 o c. the vcc (drain) to out (source) voltage is actively clamped at 55v, improving its perfor- mance during turn off with inductive loads. the on-chip charge pump high side driver stage is floating and referenced to the source of the power mosfet. thus the logic to power ground isolation can be as high as 50v. this allows operation 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 ? programmable logic controller truth table block diagram available packages condition normal normal output open output open shorted output shorted output over-temperature over-temperature in h l h l h l h l out h l h h l l l current-limiting pwm mode dg h l h h l l l l gnd out vcc gnd out vcc 5 lead smd220 5 lead to-220 v cc(op) 5-50v r ds (on) 100m ? i lim 20a t j(sd) 170c e av 200mj product summary www.irf.com 1
