DRV10983LIPWP

Overview

The DRV10983LIPWP is a three-phase sensorless BLDC motor driver manufactured by Texas Instruments. It features an integrated power stage with a total H+L rDS(on) of 250 mΩ and provides 2 A continuous winding current with 3 A peak capability. The device operates within an input voltage range of 8 V to 28 V and includes an integrated buck/linear regulator for 5 V or 3.3 V output. It utilizes a proprietary back electromotive force control scheme for continuous sine 180° commutation, eliminating the need for external sensing resistors. The component is housed in a thermally enhanced HTSSOP-24 package and supports operation from -40°C to +125°C.

Feature Summary

• Proprietary sensorless back electromotive force control enables continuous sine 180° commutation to reduce audible noise during switching.
• Integrated buck and linear regulators efficiently step down supply voltage to provide stable 5 V or 3.3 V power for internal and external circuits.
• Flexible user interface options include I2C for register access and EEPROM programming, dedicated SPEED pin for analog or PWM input, and FG pin for tachometer feedback.

Applications

• Fan motor drivers
• Cost-sensitive low-noise motor control systems
• Applications requiring minimal external component count

Procurement Notes

Verify the specific suffix 'LI' against the official Texas Instruments datasheet to confirm the exact functional variant, as suffixes often denote specific packaging, temperature grades, or feature sets. Ensure the ordering part number matches the required sleep or standby mode characteristics defined in the product selection guide. Cross-reference the HTSSOP-24 package details with your PCB footprint specifications to guarantee mechanical compatibility.

Selection Notes

Select this component when designing systems that require sensorless control of three-phase BLDC motors with high efficiency and low acoustic noise. The integrated power stage simplifies design by removing the need for external MOSFETs and gate drivers. Consider the I2C programmability for optimizing performance across different motor types without hardware changes. Evaluate the thermal performance of the HTSSOP-24 package relative to your expected continuous current load and ambient operating conditions.

Part Context

The DRV10983 series belongs to Texas Instruments' portfolio of PMIC solutions focused on motor motion and ignition controllers. This family is designed for applications demanding low external component counts and cost-effective implementations. The DRV10983LIPWP represents a specific variant within this line, utilizing the standard DRV10983 core architecture but potentially differing in specific operational modes or packaging configurations compared to other suffixes like ZPWP.

Replacement Considerations

Direct substitutes include DRV10983PWP and DRV10983ZPWP. Verify if the 'Z' suffix (sleep mode) or lack thereof aligns with your power management requirements. Ensure any replacement maintains the 24-pin HTSSOP form factor and compatible electrical parameters such as the 250 mΩ rDS(on) and 2 A continuous current rating.
