BTS3800SL - New Protected Low-Side HITFET™ for Automotive Applications

BTS3800SL block diagram

April 2011 saw Infineon release BTS3800SL, one of the world's smallest protected automotive relay driver. BTS3800SL comprises a HITFET™ switch in a SCT595 package. It offers latching, short-circuit and thermal protection in a simple three-pin device, simplifying design requirements and reducing protection circuitry around the part. 
 
BTS3800SL is designed to drive relays up to 375mA load current and is equipped with standard HITFET™ protection features. It is the first Infineon HITFET™ to come in the proven, robust SCT 595 package with linked leads for increased thermal cooling on the pins. With a total area of just 7.25mm², SCT 595 is 84% smaller than SOT 223 (which has a 45.5mm² footprint on the PCB).

Small footprint Standard HITFET™ protection features: Short-circuit and overload protection Overvoltage protection with active clamping Overtemperature protection with monolithic embedded temperature sensor
