Product Brief BTS723GW Smart High-Side Power Switch for 24V Applications, Two Channels 100mΩ Basic Functions The BTS723GW is a two channel high-side power switch (two times 100mΩ) in PG-DSO-14 power package providing embedded protection functions. The device is CMOS compatible monolithically integrated in Smart SIPMOS technology. The power transistor is built Improved electromagnetic compatibility (EMC) by N-Channel-planar power MOSFET with a charge pump which boosts the battery voltage. The inputs are ground referenced CMOS compatible. Fast demagnetization of inductive loads Stable behaviour at undervoltage Logic ground independent from load ground Wide operating voltage range Optimized inverse current Applications Resistive loads such as heating systems Inductive loads such as valves , relays on capability Protection Functions –– Heavy duty trucks –– Construction vehicles Short circuit protection –– Agricultural tractors Overload protection Replaces electromechanical relays, fuses and discrete circuits Current limitation Thermal shutdown Overvoltage protection Loss of ground and loss of Vbb Reverse battery protection with Diagnostic Functions Diagnostic feedback with open drain output Open load detection in OFF state Feedback with thermal shutdown in ON state protection external resistor Electrostatic discharge protection (ESD) [ www.infineon.com ] Product Brief BTS723GW Smart High-Side Power Switch for 24V Applications, Two Channels 100mΩ Block Diagram Status pull up voltage IN1 Vbb Logic Channel 1 ST1 IN2 Logic Channel 2 ST2 OUT1 Load1 OUT2 PROFET ™ GND Load2 Product Summary Type Description Package BTS723GW 2x 100mΩ PG-DSO-14 Parameter Value Unit Operating voltage VBAT(ON) 7.0V … 58.0V Operating current (all channels active) IGND 3.0mA Over voltage protection VBB(AZ) 69.0V ON-state resistance RDS(ON) 100mΩ Nominal load current IL(NOM) 4.2A Current limitation IL(SCr) 8.0A Slew rate (on/off) dV/dt 5V/µs Output clamp (inductive load switch off) VON(CL) 70.0V Published by Infineon Technologies AG 85579 Neubiberg, Germany © 2011 Infineon Technologies AG.
