76500001 is the identifier for an 18-pin IC (Integrated Circuit) manufactured by Topmet. It is a low voltage, low power consumption single-phase forward and reverse motor control IC. It is designed for motor control applications such as motor drivers, over-current and over-voltage protection, and motor speed control. It has two mode control modes: Pulse Width Modulation (PWM) and Phase-Locked Loop (PLL). It includes input and output amplifiers and integrators, comparators, and logic, configurable logic blocks, and the ability to provide a 7-bit resolution. Additionally, it has Error Detection & Correction (EDC) logic to protect the IC from potentially damaging events. It also has integrated driver circuitry for driving external MOSFETs for improved power handling and efficiency in higher voltage applications.
