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.

Notes:
2. Exceeding the absolute maximum ratings may damage the device.
3. The device is not guaranteed to function outside its operating ratings.
4. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5kΩ in series with 100pF.
5. Junction-to-Ambient Thermal Resistance θJA is measured using the Evaluation Board as described in section PCB Layout Recommendations.
6. Specification for packaged product only.
7. The turn-on time is defined as the time it takes from asserting CTL to VOUT reaching 90% of VIN (rising).
8. The turn-off time is defined as the time it takes from the falling edge of CTL to VOUT reaching 90% of VIN (falling).
