SGM25006

Power Distribution Switch with

Precision Adjustable Current Limit

GENERAL DESCRIPTION

FEATURES

The SGM25006 is a single channel power distribution

switch. The switch operates from a wide range of 2.5V

to 6.5V supply voltage, and is controlled by the nEN/EN

pin. The rise time and fall time of the device are

controlled internally to avoid inrush current.

● Input Voltage Range: 2.5V to 6.5V

● For USB Current Limit Requirements

● Adjustable Current Limit: 500mA to 5A

● ±5% Current Limit Accuracy at 4.5A

● Fast Over-Current Response: 3.5μs (TYP)

● On-Resistance: 20mΩ (TYP)

● Supply Current: 115μA (TYP)

● Built-in Soft-Start

An integrated charge pump biases the N-MOSFET

switch in order to achieve a low switch R_DSON. This

device provides the adjustable current limit threshold

between 500mA and 5A through the R_ILIM. If the load

current is higher than the current limit threshold, the

device will limit the output current to a safe level and

enter into constant-current mode. Fault conditions such

as over-current and over-temperature are indicated by

the nFAULT pin.

NOTE: *. In the case of short-circuit, the lead is relatively long, or the input capacitor parasitic inductance is relatively large, the

resonance may cause V_INovershoot or burning die, it is recommended that the input capacitance is above 10μF, the output

capacitance is above 1μF.
