P R O D U C T B R I E F The BTS 5215L is a dual channel high-side power switch (two times 90 mΩ) in Power SO-12 package. It is fully protected by embedded protection functions. There is one diagnostic feedback pin for each channel signalling open load and over temperature. The device is monolithically integrated in Smart SIPMOS technology. The power transistor is built by a N-channel vertical power MOSFET with charge pump. The inputs are ground referenced CMOS compatible. Basic Functions BTS 5215L Diagnostic Functions Protective Functions ■ Very low standby current ■ Short circuit protection ■ CMOS compatible input ■ Overload protection ■ Improved electromagnetic ■ Current limitation ■ Open load detection in OFF-state compatibility (EMC) ■ Thermal shutdown ■ Feedback of thermal shutdown Fast demagnetization of inductive ■ Overvoltage protection (including ■ loads ■ Stable behaviour at undervoltage ■ Wide operating voltage range ■ Logic ground independent from ■ Diagnostic feedback with open drain output in ON-state load dump) with external resistor ■ ■ load ground ■ Reverse battery protection with Applications external resistor ■ µC compatible high-side power Loss of ground and loss of Vbb switch with diagnostic feedback protection for 12 V and 24 V grounded loads Electrostatic discharge protection ■ (ESD) All types of resistive, inductive and capacitive loads ■ Most suitable for loads with high inrush currents, so as lamps ■ Replaces electromechanical relays, fuses and discrete circuits Smart High-Side Power Switch Two Channels 90 mΩ N e v e r s t o p t h i n k i n g .
