DRV8301 Three-Phase Gate Driver IC

Specifications

Product Overview

The DRV8301 is a Texas Instruments three-phase gate driver IC for Power_Management designs using external N-channel MOSFETs. Its gate-drive stage provides three half-bridge drivers, with each half-bridge driving high-side and low-side MOSFETs. Device operating supply voltage is specified from 6 to 60 V, with 1.7 A peak source and 2.3 A peak sink gate-drive capability.

Control can be implemented with 6-PWM or 3-PWM inputs, while SPI is used for parameter configuration and fault reporting. The bootstrap gate driver includes trickle-charge circuitry supporting 100% duty-cycle operation. Two integrated current shunt amplifiers provide adjustable gain through SPI registers and adjustable bidirectional output offset up to 3 V.

The IC is supplied in a 56-pin HTSSOP with PowerPAD, using a 14.00 mm x 8.10 mm body and exposed PowerPAD ground. Integrated protection and reporting include programmable dead time, programmable overcurrent protection with VDS sensing, PVDD and GVDD undervoltage lockout, GVDD overvoltage lockout, overtemperature warning and shutdown, plus nFAULT, nOCTW, and SPI register reporting.

Procurement Notes

When requesting a quote for DRV8301, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.

If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.

For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
