MIC95410
6.6mΩ RDS(ON), 7A, 5.5V VIN Load Switch in
1.2mm × 2.0mm QFN Package
General Description
The MIC95410 is a high-side load switch for computing
and ultra-dense embedded computing boards where high-
current low-voltage rails from sub-1V to 5.5V have to be
sectioned. The integrated 6.6mΩ RDS(ON) N-channel
MOSFET ensures low voltage drop and low power
dissipation while delivering up to 7A of load current.
The MIC95410 is internally powered by a separated bias
voltage from 2.7V to 9V. It includes a TTL-logic level to
gate a voltage translator driving a charge pump, and an
output discharge function when disabled. The OFF-state
current from bias supply (VS) and the power switch OFF-
state leakage current (IOFF) are both below 1µA.
The MIC95410 provides user-adjustable slew-rate-
controlled turn-on to limit the inrush current to the input
supply voltage.
The MIC95410 is available in a thermally efficient, space-
saving 10-pin 1.2mm x 2.0mm QFN package with 0.5mm
pin pitch and an operating junction temperature range from
–40°C to +125°C.
Datasheets and support documentation are available on
Micrel’s web site at: www.micrel.com.
