Overview
The DRV8436PPWPR is a dual H-bridge motor driver manufactured by Texas Instruments, designed for bipolar stepper or dual-brushed DC motors. It supports a supply voltage range of 4.5 V to 48 V and delivers up to 1.5 A full-scale output current per bridge. The device integrates current sensing and operates within an extended temperature range of -40°C to +125°C. Packaged in a 28-pin HTSSOP (PWP) with exposed pad, it features a 400 kHz operating frequency and draws 5 mA of quiescent supply current.
Feature Summary
- Integrated current sensing capability for precise motor control
- Supports both bipolar stepper and dual-brushed DC motor topologies
- Extended thermal performance rated for high ambient temperatures
Applications
- Bipolar stepper motor drive systems
- Dual-brushed DC motor control applications
- Industrial automation equipment requiring integrated half-bridge drivers
Procurement Notes
Verify the specific suffix PWP confirms the HTSSOP-28 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure PCB layout accommodates the exposed thermal pad for adequate heat dissipation given the 1.5 A current rating. Validate that the 48 V maximum supply voltage aligns with the system power architecture.
Selection Notes
Select this component when a single IC solution is required for driving two independent brushed DC motors or one bipolar stepper motor. The integrated current sensing reduces external component count compared to discrete solutions. Consider the HTSSOP-28 package constraints regarding thermal management and pin pitch compatibility during board design. Verify that the 4.5 V minimum logic supply meets the controller interface requirements.
Part Context
This part belongs to the DRV8436E/P family of motor drivers from Texas Instruments. It serves as a compact alternative to discrete MOSFET implementations for low-to-medium power motor applications. The device consolidates gate drivers, protection circuits, and current sensing into a single surface-mount package, simplifying the bill of materials for motor control designs.
Replacement Considerations
The DRV8436ERGER is a related variant within the same family offering similar electrical characteristics but housed in a VQFN-24 package. Designers must account for differences in thermal dissipation capabilities and footprint dimensions when substituting between the HTSSOP and VQFN packages.
