DRV8303DCAR

Overview

The DRV8303DCAR is a three-phase pre-driver integrated circuit manufactured by Texas Instruments, designed for brushless DC motor control applications. It operates within a supply voltage range of 6 V to 60 V and supports an output current of 1.7 A with a quiescent supply current of 15 mA. The device features two low-side current shunt amplifiers and utilizes an SPI interface for configuration. It is housed in a 48-pin HTSSOP package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

Integrates dual low-side current sense amplifiers for precise current monitoring
Supports bidirectional current detection with adjustable output offset
Features SPI interface for flexible parameter configuration and fault reporting

Applications

Brushless DC (BLDC) motor control systems
Pump and compressor drive applications
Robotics and remote-controlled toy mechanisms

Procurement Notes

Verify the specific suffix 'DCAR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 48-pin HTSSOP footprint matches the target PCB layout dimensions. Ensure compatibility with the system's voltage levels and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when a dedicated pre-driver with integrated current sensing is required for three-phase motor drives. It is suitable for designs needing SPI-based control rather than direct PWM inputs. Consider the 48-pin package size and the need for external high-side and low-side MOSFETs to complete the power stage implementation.

Part Context

This part belongs to the DRV8303 family of three-phase pre-drivers from Texas Instruments. It is distinct from the DRV8301 series, which includes an integrated buck converter. The DRV8303 focuses on providing gate drive signals and current sensing capabilities without an onboard regulator, requiring external power management for logic supplies.
