GMT G5197 3a capable slew rate controlled load switch with true reverse current blocking. Datasheet

G5197
Global Mixed-mode Technology
3A Capable Slew Rate Controlled Load Switch
With True Reverse Current Blocking.
Features
General Description
„ Input Voltage Range 1.5V to 5.5V
„ Typical RON:
The G5197 advanced load-management switches target
applications requiring a highly integrated solution. If
disconnects loads powered from DC power rail (<6V) with
stringent off-state current targets and high load
capacitances (up to 200µF). Each switch consists of
slew-rate controlled low-impedance MOSFET switch
(23mΩ type) and other integrated analog features. The
slew-rate controlled turn-on characteristic prevents inrush
current and the resulting excessive voltage droop on
power rails.

requirement.
reverse current from VOUT to VIN during ON/OFF state.
The package is WLCSP2X3 -6
These device have exceptionally low off state current
drain (<2µA max) which facilitate compliance in very low
stand by power applications. The input voltage range
operates from 1.5V to 5.5V DC to support a wide range of
applications in consumer. Optical, medical storage,
portable and industrial device power management.
Switch control is managed by a logic input (Active HIGH)
capable of interfacing directly with low voltage control
signal/GPIO with no extremely pull-down resistor
required.
Applications
„ Cellular Phones
„ Portable Navigation Devices(PND)
„ Personal Media Players (PMP)
„ Ultra Mobile PCs
„ Portable Instrumentation
„ Other Portable Applications
„ PDAs
„ Industrial and DataComm Equirment
The device is packaged in WLCSP2X3 -6 pin.
