Product Overview
The DRV8316 is a Texas Instruments three-phase BLDC motor driver for Power_Management designs using typical 12 V or 24 V motors below 80 W. It integrates three 1/2-H bridges with an N-channel power MOSFET output stage and supports a normal operating supply range of 4.5-35 V, with a 40 V absolute maximum on the VM pin.
The output stage supports 8 A peak output current and has 95 mΩ high-side plus low-side MOSFET on-state resistance at TA=25°C. Motor-control interfaces include configurable 6x PWM and 3x PWM modes, both with cycle-by-cycle current-limit support. Integrated current sensing removes the need for external current sense resistors.
The device is supplied in a 40-pin VQFN package, 7.00 mm x 5.00 mm. DRV8316R provides a 5 MHz, 16-bit SPI interface for configuration and fault status, while DRV8316T uses pin-based hardware configuration. Integrated regulators include a 3.3 V ±5% AVDD LDO rated for 30 mA and a 3.3 V or 5 V buck regulator rated for 200 mA.
