描述 Description

DESCRIPTION
The µPD16876 is a power switch IC with an overcurrent limiter that is used for the power bus of a Universal Serial Bus (USB). This product has one Pch power MOSFET circuits, which has a low-on resistance (100 mΩ TYP.), in its switching block. This product boasts an operating current consumption of as low as 100 µA (MAX.).
In addition, the IC is also equipped with an overcurrent detector that is essential for a host/hub controller  conforming to the USB Standard, so that the IC can report an overcurrent to the controller. Moreover, a thermal shutdown circuit and an undervoltage lockout circuit are also provided as the protection circuits of the IC.
This product has one channel of power switch, control input pin, and flag output pin to simultaneously control one USB port with a single IC.FEATURES
• One P-ch power MOSFET circuit
• Overcurrent detector that outputs active-low control signal from detection report pin
• Overcurrent limiter to prevent system voltage drop
• Thermal shutdown circuit
• Undervoltage lockout circuit
• This control circuit can be turned on and off independently of the others by a control pin.
• 8-pin SOP package
