Datasheet Summary with AI

# US2026A CMOS IC
## DUAL-CHANNEL USB POWER SWITCH AND OVER-CURRENT PROTECTION

Features
· Two P-channel power MOSFET control switches
· 110µA Max operating current
· 5µA Max standby current
· 145 mΩ Max switch resistance
· 2.7V ~ 5.5V input voltage range
· 500mA minimum continuous load current
· Smooth turn-on minimizes in-rush voltage drop
· 1 ms fault flag delay
· Over-current protection
· Under-voltage lockout
· Thermal shutdown protection
· Fault flag indicates fault conditions

Pin Descriptions
· EN1/EN2: Enable inputs for switch 1 & 2
· FLAG1/FLAG2: Active-low, open-drain fault flags for switch 1 & 2
· OUT1/OUT2: Output drains for switch 1 & 2
· IN: Power input (source)
· GND: Ground

Electrical Characteristics
· VIN: 2.7V - 5.5V
· IOUT: 500mA (each output)
· R ON: 105-180 mΩ (typical)
· V UVLO: 2.3V (typical)
· Thermal Shutdown: 145°C (activation), 135°C (hysteresis)

Protection Features
· Over-Current Protection: Internal current limit threshold
· Thermal Shutdown: Turns off switches if junction temperature exceeds 145°C
· Under-Voltage Lockout (UVLO): Prevents operation below 2.3V
