DRV3201 Three-Phase BLDC Motor Pre-Driver IC for Electric Power Steering / Column Drive Modules

The DRV3201 is a highly integrated three-phase brushless DC (BLDC) motor pre-driver integrated circuit, specifically engineered for demanding automotive applications like electric power steering (EPS) and column drive modules.

This device serves as a critical control component for steering computer boards, providing the precise drive signals needed to control high-power N-channel MOSFETs in the motor control stage.

The chip is designed to handle a substantial gate charge of up to 250 nC, with a programmable gate current drive from 140 mA to 1 A for flexible output slope adjustment.

It supports a wide operating voltage range from 4.75 V to 30 V, and includes an integrated boost converter that ensures full power-stage control even during severe low battery conditions.

An integrated SPI interface provides sophisticated diagnostic, protection, and monitoring capabilities, including features like overcurrent protection, overtemperature warning, and short-circuit protection.

The device also incorporates two high-accuracy current sense amplifiers and three real-time phase comparators, enabling precise motor control and efficient operation.

AEC-Q100 qualified for Grade 1 operation, this driver operates reliably across a -40°C to +125°C ambient temperature range.

With advanced shoot-through protection and programmable dead time, the DRV3201 is designed to support safety-critical automotive applications, a trait recognized in its capability to assist in designing systems that meet ASIL-D requirements.

This component is an ideal, high-quality replacement part for professionals repairing electronic power steering and other critical motor control modules.
