SGM2576/SGM2580/81/83/88 Series Low Ron, High Precision Power Distribution Switches

SGMICRO has recently introduced a series high precision power distribution switches with internal resistance as low as 100mΩ: SGM2576/SGM2580/81/83/88. The series operates over an input voltage range of 2.5V to 5.5V, and the output current limit can be chosen from 1.1A, 2.1A, 2.6A or adjustable. The series is intended for self-powered and bus-powered Universal Series Bus (USB) applications. SGM2576 can provide up to 2.5A of continuous load current and offers a programmable current limit threshold between 400mA and 2.5A via an external resistor. SGM2580/SGM2581/SGM2583/SGM2588 have fixed output current limit with three current limit levels to choose from: 1.1A, 2.1A and 2.6A.

The series limits the output current to a safe level by using a constant-current mode when the output load exceeds the current limit threshold. An internal reverse-voltage comparator disables the power switch when the output voltage is driven higher than the input to protect devices on the input side of the switch.

SGM2576/SGM2580/81/83/88 are available in the Green SOT-23-5 package. The rated temperature range for the series is from -40°C to +85°C.
