HIP4082IP

Full Half-Bridge (H Bridge) Drivers Overview

The HIP4082IP is an 80V, 1.25A peak current H-Bridge FET Driver IC designed for medium frequency and voltage applications. It independently drives four N-channel FETs in half-bridge or full-bridge configurations. The device supports a bootstrap supply maximum voltage of 95VDC and can drive a 1000pF load in free air at 50°C with typical rise and fall times of 15ns. It features user-programmable dead time ranging from 0.1 to 4.5µs, making it suitable for switching frequencies up to 200kHz. Input logic thresholds are compatible with 5V to 15V logic levels.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix of the ordered part number to confirm package type and lead-free status. The HIP4082IP denotes a PDIP-16 through-hole package. Ensure compatibility with RoHS standards if lead-free operation is required, as standard versions may contain lead. Confirm that the application environment supports the specified operating temperature range and voltage limits before finalizing procurement.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select the HIP4082IP for moderate power level applications requiring operation up to 80V. It is ideal for designs needing a wider range of programmable dead times compared to similar models like the HIP4081. Choose this component when smaller packaging is preferred due to reduced drive current requirements. Ensure the system design accommodates the lack of an internal charge pump by implementing appropriate bootstrap circuitry for upper drive circuits.

Full Half-Bridge (H Bridge) Drivers Part Context

The HIP4082 is part of Intersil's H-bridge driver family, specifically targeted at PWM motor control and UPS applications. It shares similarities with the HIP4081 but offers reduced drive current and a wider range of programmable dead times. The device simplifies bridge-based designs by providing flexible input protocols and comprehensive protection features, excluding shoot-through conditions.
