With Reversave reverse battery protection, diagnostic current sense feedback (13,000:1 ratio), and comprehensive protection (overload, overtemperature, overvoltage, output clamp), it is AEC-Q101 qualified for high-current automotive and industrial 24V load switching applications.","working_principle":"The BTS50085-1TMB integrates an N-channel vertical power MOSFET with charge pump, control logic, and protection circuitry using Infineon's Smart SIPMOS chip-on-chip technology. The internal charge pump generates a gate voltage above Vbb to fully enhance the N-channel MOSFET, achieving 7.2 m\u03a9 on-resistance. The IN pin (active-low) controls the switch state through a current-controlled input. The IS (current sense) pin provides an analog output proportional to the load current at a ratio of 13,000:1, enabling load monitoring and fault detection. During reverse battery conditions, the Reversave feature allows the MOSFET body diode to conduct, turning on the MOSFET in the reverse direction with low resistance, protecting the circuit. The output clamp (62V typical) safely demagnetizes inductive loads by clamping the output voltage during turn-off. The overtemperature protection shuts down the device when junction temperature exceeds the threshold, auto-restarting after cooling.","pin_description":"\n
