: Monitors line input trends for precise AC overvoltage and undervoltage cutoff thresholds. Key Technical Specifications & Electrical Limits

Here’s the best way to proceed:

Multiplier AC sine wave input. It connects to the rectified mains voltage via a resistor divider to achieve a high power factor. Gate drive output for the external power MOSFET

The datasheet specifies the maximum input voltage, junction temperature, and power dissipation. Exceeding these values—even momentarily—can destroy the IC. For example, one variant of the 8650 series has an absolute maximum of 45V, but the recommended operating range is 8-40V.

Current sensing pin; monitors voltage across a high-precision resistor. System and power ground. DRV Totem-pole output to drive the external power MOSFET. VDD Main power supply for the IC. OTP Sets the temperature foldback point for thermal protection. OVP Input line voltage over-voltage protection. Protection Mechanisms

:

Features a unique output current foldback based on temperature, which protects the system by reducing current as heat increases.

Universal AC (typically 85V - 300V AC). Operating Voltage (VDD): 9.5V to 27V.

Zero-crossing detection; also used for over-voltage protection (OVP) . Power supply pin . DRV RN NTC resistor connection for thermal compensation
