Integrating an N-channel vertical power FET with charge pump, current sense (13,000:1 ratio), and comprehensive protection (OCP, OTP, OVP, load dump), it is designed for 12V automotive and industrial high-current load driving applications in a PG-TO220-7-11 package.","working_principle":"The BTS50085-1TMB integrates an N-channel vertical power MOSFET with all necessary control and protection circuitry. The internal charge pump generates a gate voltage above the supply rail to fully enhance the N-channel MOSFET, enabling the low 9 m\u03a9 on-resistance. The current-controlled input pin (IN) activates the switch when pulled to ground. The IS pin provides a diagnostic sense current proportional to the load current at a 13,000:1 ratio, enabling real-time load monitoring. Protection circuits include overcurrent limitation (90A), overtemperature shutdown with auto-restart, overvoltage clamping at 70V, and load dump protection to 80V. The output clamp (VON(CL) = 62V) protects against inductive kickback when switching off inductive loads.","pin_description":"\n
