HIP2104FRAANZ-T7A

Gate Driver Overview

The HIP2104FRAANZ-T7A is a half-bridge gate driver manufactured by Renesas Electronics Corporation. It features a maximum bootstrap supply voltage of 60V and includes dedicated 3.3V and 12V LDOs with enable pins. The device operates within a temperature range of -40°C to +125°C and utilizes an 8-lead SOIC package. Key electrical parameters include a peak pull-up current of 1A, a peak pull-down current of 2A, a turn-on propagation delay of 28ns, and a turn-off propagation delay of 30ns.

Gate Driver Feature Summary

• Integrates dedicated 3.3V and 12V low-dropout regulators with independent enable controls for flexible power management.
• Features an integrated bootstrap FET that eliminates the need for external bootstrap diodes in high-side driving applications.
• Includes internal pull-down resistors on all input pins to reduce external component requirements and simplify circuit design.
• Provides active-low resistance pull-down on the LO output to ensure the low-side bridge FET remains off during sleep mode or undervoltage lockout conditions.

Gate Driver Applications

• DC motor control systems
• Three-phase brushless DC motor drives
• General inductive load switching

Gate Driver Procurement Notes

Verify the specific suffix T7A corresponds to tape-and-reel packaging when sourcing. Confirm RoHS compliance status as required by project specifications. Check manufacturer lifecycle notices for obsolescence warnings, as this component may be subject to discontinuation. Ensure compatibility with existing PCB footprints for the 8-lead SOIC package before finalizing procurement decisions.

Gate Driver Selection Notes

Select this component for designs requiring integrated LDOs and bootstrap solutions to minimize external bill of materials. Consider the 60V bootstrap limit and 1A/2A peak currents when sizing external MOSFETs. Evaluate the -40°C to +125°C operating range against environmental constraints. Compare propagation delays against switching frequency requirements to ensure adequate dead-time control.

Gate Driver Part Context

This part belongs to the HIP210x series of half-bridge drivers from Renesas. It shares functional similarities with the HIP2103 but adds integrated voltage regulators. The series targets motor control and industrial applications requiring robust gate driving capabilities with simplified peripheral circuitry.

Gate Driver Replacement Considerations

HIP2103FRTAAZ serves as a direct alternative lacking the integrated LDOs. Verify pin compatibility and check if the absence of onboard regulators meets the system power architecture requirements before substitution.

Gate Driver FAQ

Does the HIP2104FRAANZ-T7A require an external bootstrap diode?

No, the device integrates a bootstrap FET internally, which replaces the traditional external bootstrap diode typically needed in half-bridge configurations.

What is the purpose of the VDen and VCen pins?

These pins are dedicated enable inputs for the integrated 3.3V and 12V LDOs, allowing independent control of these voltage regulators to optimize power consumption.
