Description

The HIP2500 is a high voltage integrated circuit (HVIC) optimized to drive N-Channel MOS gated power devices in half bridge topologies. It provides the necessary control for PWM motor drive, power supply, and UPS applications. The SD pin allows external shutdown of gate drive to both upper and lower gate outputs. Undervoltage lockout will not allow gating when the bias voltage is too low to drive the external switches into saturation.
