ZXMS6003G 60V N-channel self protected enhancement mode TM IntelliFET MOSFET with programmable current limit Summary Continuous drain source voltage V = 60V DS On-state resistance 500m Nominal load current (V = 5V) 1.4A IN Clamping energy 550mJ Description Self protected low side MOSFET. Monolithic over temperature, over current, over voltage (active S clamp) and ESD protected logic level functionality. Intended as a general purpose switch, with status D Status indication and programmable current limit. Rprog IN Top view Note: Rprog must be connected between the Status and IN pins Features Current limit programmable via external Over-current protection resistor Input Protection (ESD) Status pin (analog status indication) Load dump protection (actively protects Short circuit protection with auto restart load) Over voltage protection (active clamp) Logic Level Input Thermal shutdown with auto restart High continuous current rating Ordering information Device Part mark Reel size Tape width Quantity (inches) (mm) per reel ZXMS6003GTA ZXMS6003 7 12 1,000 Issue 2 - March 2007 1 www.zetex.com Zetex Semiconductors plc 2007ZXMS6003G Functional block diagram Status / D current limit Over voltage protection IN Over current protection Human body Logic ESD protection Over temperature protection S Applications and information Especially suited for loads with a high in-rush current such as lamps and motors. All types of resistive, inductive and capacitive loads in switching applications. C compatible power switch for 12V and 24V DC applications. Automotive rated. Replaces electromechanical relays and discrete circuits. Linear mode capability - the current-limiting protection circuitry is designed to de-activate at low V , in order not to compromise the load current during normal operation. The design DS max. DC operating current is therefore determined by the thermal capability of the package/ board combination, rather than by the protection circuitry. Note: This does not compromise the product s ability to self-protect during short-circuit load conditions. The current limit is programmable via an external resistor R connected between Status and prog IN pins. Status pin voltage reflects the gate drive being applied internally to the power MOSFET. With V = 5V and R = 24k : IN prog Status voltage ~ 5V indicates normal operation. Status voltage ~ (2-3)V indicates that the device is in current-limiting mode. Status voltage < 1V indicates that the device is in thermal shutdown. Issue 2 - March 2007 2 www.zetex.com Zetex Semiconductors plc 2007
