GS9121 1.0A/2.0A High-Side Power Switch With Flag Product Description The GS9121 serial products are high-side power switch with 80mΩ RDS(ON), available with 1.0A and 2.0A continuous output capability. They are suitable for 3.0V, 3.3V and 5.0V power rail. GS9121 has enable pin with selectable active high or active low level. It has output discharge feature. It has FLAG pin to indicate the chip status, active low with open drain output once OCP, load short, OTP or OUT-to-IN reverse event is triggered. GS9121 has lower quiescent current as 25uA making this device ideal for portable battery-operated equipment. Available Package: SOT-23-5L. Block Diagram Features  Integrated high-side Power MOS: 80mΩ(Typ.)  Operation Voltage: 2.5V to 5.
