Description

The DIO7495 load-management switch is designed

for applications that demand a highly integrated

solution. It disconnects loads powered from the DC

power rail (< 5.5 V) with high load-capacitance and

strict off-state current targets. The DIO7495 has both

over-current protection and over-voltage protection.

Unwanted reverse current from VOUT to VIN during ON

and OFF states is stopped by the real reverse-current

blocking (RRCB) function. The low off-state current

drain (< 2 μA maximum) is utilized to help meet

standby power conditions. To support a wide range of

applications in storage, such as medical, consumer,

optical, and industrial-device power management, the

input voltage will operate from 2.5 V to 5.5 V DC.

Switch control is handled by a logic input (Active

HIGH) that can interact directly with low-voltage

control signal/general-purpose input/output (GPIO)

without the assistance of an external pull-down

resistor. The DIO7495 is packaged in flip-chip

QFN1.2*1.2-9.
