HIP4080IP

Full Half-Bridge (H Bridge) Drivers Overview

The HIP4080IP is an 80V, 1.25A peak current H-bridge FET driver IC designed for medium-frequency, medium-voltage applications. It integrates independent drivers for four N-channel FETs in half-bridge or full-bridge configurations. The device features a bootstrap power supply with a maximum voltage of 95VDC and user-programmable dead time ranging from 0.1 to 4.5µs. It supports logic input thresholds compatible with 5V to 15V signals and includes protection against shoot-through conditions. Packaged in a 16-pin plastic SOIC (N) or DIP, it operates within a temperature range of -55°C to +125°C.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix for lead-free compliance when ordering, as indicated by the 'Z' designation in part numbers like HIP4082IBZ. Confirm package type requirements, noting that PDIP variants are intended for through-hole wave soldering processes rather than surface mount reflow. Ensure the selected variant matches the required operating temperature range and pin configuration for your PCB layout.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for applications requiring robust H-bridge control without internal charge pumps. It is suitable for designs where external bootstrap capacitors are preferred or where higher drive currents found in the HIP4080A/A variants are unnecessary. Consider the programmable dead time flexibility for optimizing switching frequencies up to 200kHz while maintaining efficiency and minimizing power loss in motor or amplifier circuits.

Full Half-Bridge (H Bridge) Drivers Part Context

This device belongs to the HIP408x family of H-bridge drivers from Intersil (now Renesas). While similar to the HIP4081, the HIP4080 series offers reduced drive current to allow for smaller package options. These drivers are optimized for cost-sensitive and size-constrained environments, providing essential bridge control functions for industrial and consumer electronics without the complexity of integrated charge pumps.
