BTS 452T/R and BTS 462T – PROFET™ high-side switches in a power package

BTS 452T/R, BTS 462T block diagram

BTS 452T/R (200 mΩ) and BTS 462T (100 mΩ) are protected high-side switches in Infineon’s MiniPROFET™ line. While most MiniPROFET™ products come in low-power DSO-8 or SOT-223 packages, the BTS 452T/R and BTS 462T are packaged in a DPAK for greater thermal capability, keeping the PCB cooler in the case of thermal toggling or soft shorts. The DPAK also provides better cooling than overmolded packages like the DSO-8 or SOT 223.

In addition to extensive protective features, the BTS 452, BTS 462 and BTS 428L2 also have a common pinout and footprint to allow easily scalable solutions. The BTS 452R includes a diagnostic feature. Both the BTS 452 and BTS 462 support an extended operational voltage range for 24 V or high-current applications. These products are fully qualified according to stringent AEC-Q100 standards.

Protection against short-circuits, overload, overtemperature, loss of Vbb and GND, overvoltage, reverse battery polarity Very low standby current Open load detection (BTS 452R) in OFF state Common pinout and footprint Scalable from 200 mΩ switch to 100 or 60 mΩ switch

All types of resistive (e.g. 5-10 W bulbs), inductive (e.g. relays) and capacitive loads Replaces electromechanical relays, fuses and discrete circuits
