WT7683P

The WT7683P is a highly integrated power supply supervisor. It is designed for single power source applications. the WT7683P minimizes external components by integrating low side current monitors, temperture monitors, FAN speed controller and an 8-bit MCU to allow small form factor and low BOM cost. Wide operating voltage range (5V to 24V) supports the commonly used operating voltages of the product. One-Time-Programmable ROM is provided for program code and user configuration data.
