Texas Instruments DRV10983ZPWP

Overview

DRV10983ZPWP from Texas Instruments is a 12- to 24-V, three-phase sensorless BLDC motor driver IC with integrated 250-mΩ H+L rDS(on) MOSFETs, delivering 2-A continuous winding current (3-A peak), and featuring an integrated 3.3-V/5-V step-down regulator, I²C interface, and dedicated SPEED/DIR/FG pins for fan and HVAC motor control.

For engineers reviewing the DRV10983ZPWP datasheet, DRV10983ZPWP pinout, DRV10983ZPWP application, or DRV10983ZPWP equivalent, key selection considerations include sleep-mode supply current (180 µA), sensorless BEMF commutation, thermal shutdown at 150°C, and HTSSOP-24 package compatibility with PCB thermal pad requirements.

Technical Context

The DRV10983ZPWP implements a proprietary sensorless back-EMF detection algorithm enabling continuous sinusoidal 180° commutation-reducing acoustic noise in low-RPM applications. It integrates a buck/linear step-down regulator with VREG output configurable for 3.3 V or 5 V, supporting external microcontroller power without discrete LDOs.

Motor control is enabled via three independent interfaces: analog/PWM SPEED input (with 320-µs sample period), DIR pin for forward/reverse logic, and FG open-drain tach output. Protection includes phase-to-phase overcurrent (4-A trip), UVLO (7.4-V rise threshold), lock detection (0.3-s enter time), and thermal shutdown with 10°C hysteresis.

Key Specifications

Pinout & Package

FAQ

What is the key difference between DRV10983ZPWP and DRV10983PWP?

The DRV10983ZPWP operates in sleep mode with 180 µA quiescent current, shutting down its internal regulator and core logic when idle. In contrast, the DRV10983PWP uses standby mode (3 mA), keeping the regulator active to sustain external circuit power. This makes DRV10983ZPWP optimal for battery-critical or always-on low-power systems, while DRV10983PWP suits designs needing uninterrupted MCU supply. Both share identical pinout, firmware, and motor control features.

Does DRV10983ZPWP require an external current sense resistor?

No, DRV10983ZPWP does not require an external current sense resistor. It implements phase-to-phase overcurrent protection using internal MOSFET Rds(on) sensing, with a typical trip threshold of 4 A. An external resistor may optionally be added only if precise power monitoring is needed-this is explicitly supported via dedicated sense terminals and register-accessible current measurement, but is not necessary for basic protection or operation of DRV10983ZPWP.

How is thermal management handled on the DRV10983ZPWP HTSSOP package?

The DRV10983ZPWP uses a 24-pin HTSSOP (PWP) package with an exposed thermal pad that must be soldered directly to the PCB ground plane. TI specifies 1.1°C/W junction-to-case (bottom) thermal resistance, requiring ≥4 thermal vias under the pad connected to an internal ground layer. Without proper thermal pad attachment, junction temperature can exceed 125°C at 2-A load-making this mechanical implementation mandatory, not optional, for reliable operation of DRV10983ZPWP.

Can DRV10983ZPWP drive a motor directly from a 12-V supply?

Yes, DRV10983ZPWP supports 12-V nominal operation within its 8–28-V input range. Its integrated MOSFETs (250-mΩ H+L rDS(on)) deliver 2-A continuous current at 12 V with acceptable thermal rise when properly heatsinked. The device's UVLO (7.4-V rise threshold) prevents startup during brownout, and its 150°C thermal shutdown protects against sustained overload-making DRV10983ZPWP suitable for 12-V fan and blower applications without additional voltage conditioning.

What interfaces does DRV10983ZPWP support for motor speed control?

DRV10983ZPWP supports three independent speed control interfaces: (1) analog voltage (0–3.3 V) on the SPEED pin with 100-mV zero-speed threshold, (2) PWM signal (1–100 kHz) on the same SPEED pin, and (3) I²C register writes to SpdCtrl[8:0] for digital command. All methods coexist-e.g., I²C can configure spin-up profile while analog input sets runtime speed-providing flexibility for different system architectures using DRV10983ZPWP.
