Overview
The DRV8436ERGER is a half-bridge stepper motor driver manufactured by Texas Instruments, designed for bipolar stepper or dual brushed DC motors. It operates within a supply voltage range of 4.5 V to 48 V and delivers an output current of 1.5 A. The device features a maximum operating frequency of 400 kHz and a quiescent supply current of 5 mA. It supports a load voltage rating of 24 V and includes two outputs. The component functions reliably across a temperature range of -40°C to +125°C. It utilizes a surface-mount VQFN-24 package with dimensions of 4x4 mm.
Feature Summary
- Integrated control and power stage for seamless motor driving
- Supports PWM interface for precise motion control
- Capable of handling bipolar stepper and dual brushed DC motor types
Applications
- Bipolar stepper motor control systems
- Dual brushed DC motor drive applications
- Industrial automation equipment requiring compact motor drivers
Procurement Notes
Verify the specific suffix 'ERGER' against the official Texas Instruments datasheet to confirm the exact packaging configuration and RoHS compliance status. Ensure that the ordering quantity aligns with the manufacturer's standard reel size requirements. Cross-reference the Mouser part number 595-DRV8436ERGER for accurate distributor identification. Confirm lead times directly with authorized suppliers as production cycles may vary based on current inventory levels.
Selection Notes
Select this component when a 1.5 A output current is sufficient for the target motor application. The 48 V maximum supply voltage makes it suitable for low-to-medium voltage systems. Consider the VQFN-24 package for space-constrained designs requiring surface mount technology. Evaluate the 400 kHz switching frequency against noise and efficiency requirements. Compare against higher current variants like the DRV8434 if increased torque is needed.
Part Context
This part belongs to the DRV8436E series from Texas Instruments, categorized under Motor / Motion / Ignition Controllers & Drivers. It is classified as a Half Bridge type within the PMIC - Power Management ICs subcategory. The series is designed for integrated motor control solutions, offering a compact alternative to discrete driver implementations.
Replacement Considerations
The DRV8436PRGER is identified as a parameter-equivalent substitute in public distributor records. Verify compatibility regarding package variations and specific electrical tolerances before substitution.
