ZXMS81045SPQ-13 Image

The ZXMS81045SPQ-13 from Diodes Incorporated is an Automotive Qualified, Intelligent High Side Switch IC that is ideal for high-side switching with diagnostic feedback for 12 V grounded leads, resistive, inductive, and capacitive loads, high in-rush current loads in incandescent lamps and motors, and compact low-power replacement for relays, fuses, and discrete circuit applications. It requires an input voltage of 5-28 V. The switch IC consists of a control logic, monolithic N-Channel vertical power MOSFET, analog current sense mirror, current limiter, charge pump gate supply, output voltage drop regulator, over-temperature detection with auto-restart, and open-load detection circuit. It is designed to offer protective and diagnostic functionalities to the circuit.

This AEC-Q100 qualified IC detects abnormal events under open-load conditions using load-current sensing in ON state and output voltage detection in OFF state. It offers proportional load current-sense output by ensuring high accuracy even at very low load currents, providing linear voltage drop to maintain sense, logic input drive, and a defined temperature and current dependency. The RoHS-compliant power switch integrates over-voltage protection (OVP), stable under-voltage protection (UVLO), electrostatic discharge (ESD) protection, loss of ground protection with external components, and enhanced short-circuit protection (SCP) to prevent over-load-related damages. It is available in a surface-mount package that measures 4.85 x 5.90 x 1.40 mm.
