一,产品概述(General Description)
     The JTM4610 SmartSwitch is a current limited P-channel MOSFET power switch designed for high-side load switching applications. This switch operates with inputs
ranging from 2.4V to 5.5V, making it ideal for both 3V and 5V systems. An integrated current-limiting circuit protects the input supply against large currents which may cause the supply to fall out of regulation. The JTM4610 is also protected from thermal overload which
limits power dissipation and junction temperatures. It can be used to control loads that require up to 1A. Current limit threshold is programmed with a resistor from SET to ground. The quiescent supply current is typically a low 9µA. In shutdown mode, the supply current
decreases to less than 1µA.
      The JTM4610 is available in a Pb-free 5-pin SOT23 or 8-pin SC70JW package and is specified over the -40°C to +85°C temperature range.

Pin Number	Symbol	Function
1	OUT	P-channel MOSFET drain. Connect a 0.47µF capacitor from OUT to GND.
2	GND	Ground connection.
3	SET	Current limit set input. A resistor from SET to ground sets the current limit for the switch.
4	ON	Enable input. Two versions are available, active-high and active-low. See Ordering Information for details.
5	IN	P-channel MOSFET source. Connect a 1µF capacitor from IN to GND.
