DRV10983ZPWP

Overview

The DRV10983ZPWP is a three-phase sensorless BLDC motor driver from Texas Instruments, designed for cost-sensitive and low-noise applications. It integrates power MOSFETs to deliver up to 2A continuous drive current with a 3A peak capability. The device operates on an input voltage range of 8V to 28V and utilizes a proprietary sensorless control scheme for continuous sine 180° commutation, significantly reducing audible noise during switching. It features a flexible user interface supporting I2C, PWM, and analog inputs, along with integrated step-down/linear regulators for internal and external circuit power supply.

Feature Summary

• Proprietary sensorless control scheme providing continuous sine 180° commutation to minimize acoustic noise
• Integrated high-side and low-side power MOSFETs eliminating the need for external sensing resistors
• Flexible interface options including dedicated SPEED pin for analog or PWM input and FG pin for tachometer feedback
• Built-in step-down and linear regulators efficiently generating 5V or 3.3V for internal and external loads

Applications

• Home appliances requiring low-noise fan and pump motors
• Industrial automation systems utilizing brushless DC motors
• Automotive cooling and ventilation fans
• HVAC equipment blower motors

Procurement Notes

Verify the specific suffix 'Z' indicates the sleep mode variant with 180µA standby current, distinct from the standard standby version. Confirm package integrity for the HTSSOP-24 form factor upon receipt. Ensure ESD precautions are observed during handling due to moisture sensitivity classification. Cross-reference ordering part numbers with official Texas Instruments documentation to avoid confusion with similar family members like the DRV10983PWPR.

Selection Notes

Select this component when application requirements demand minimal external component count and reduced electromagnetic interference through sinusoidal commutation. The integrated power stage simplifies PCB layout compared to discrete solutions. Consider the sleep mode current consumption if battery backup or ultra-low power states are critical. Evaluate thermal performance within the -40°C to +125°C operating range to ensure reliability under varying environmental conditions.

Part Context

This device belongs to the DRV10983 family of three-phase BLDC motor controllers. It shares core architecture with variants like the DRV10983PWPR but differs in standby current specifications. The Z suffix denotes the sleep mode configuration, optimizing power efficiency when the motor is stationary. It serves as a complete solution for driving small to medium-sized brushless motors without external gate drivers.

Replacement Considerations

DRV10983PWPR: Standard standby mode variant with higher quiescent current than the Z suffix version.

FAQ

What is the difference between the DRV10983ZPWP and the standard DRV10983?

The DRV10983ZPWP features a sleep mode with a typical supply current of 180µA, whereas the standard DRV10983 typically offers a standby mode with a higher current consumption of 3mA.

Does the DRV10983ZPWP require external current sensing resistors?

No, the device is designed to operate without external sensing resistors by using its proprietary sensorless control scheme, though users can add them externally if active current monitoring is desired.
