DRV8812PWPR Equivalent & Substitute Parts

Part Overview

The DRV8812PWPR is a bipolar motor driver IC manufactured by Texas Instruments, designed for brushed DC and stepper motor applications. This fully integrated driver combines control and power stage functionality in a 28-PowerTSSOP surface mount package. The device operates across a supply voltage range of 8.2V to 45V with an output current capability of 1.6A and supports half-bridge output configuration with parallel interface control. The part is Active status and ROHS3 compliant, making it suitable for general-purpose motor control applications requiring robust thermal performance across -40°C to 150°C operating temperature range.

Substitute parts become necessary when addressing specific application requirements such as alternative interface protocols, different output configurations, or packaging constraints while maintaining functional compatibility with bipolar motor driving applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRV8812PWPR is determined by compatibility across the following critical parameters:

• Motor type support (Bipolar stepper and brushed DC capability)
• Fully integrated driver architecture (control and power stage combined)
• Power MOSFET technology
• Surface mount implementation
• Active product status and ROHS3 compliance

The substitute parts DRV8436ERGER, DRV8436PRGER, and DRV8436RGER share the same manufacturer (Texas Instruments), motor type support, integrated driver function, and MOSFET technology. However, these substitutes differ in interface protocol (PWM or Step/Direction versus Parallel), output configuration (Half Bridge 2 versus Half Bridge 4), and package form factor (24-VQFN versus 28-PowerTSSOP). These differences require evaluation based on specific application interface requirements and PCB layout constraints.

Parameter Comparison

Engineering Selection Recommendations

All parts in this comparison maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment for industrial applications.

The DRV8812PWPR operates with a supply voltage range of 8.2V to 45V and supports four half-bridge outputs with parallel interface control. This configuration is suitable for applications requiring direct parallel logic control and higher supply voltage operation.

The DRV8436ERGER and DRV8436PRGER variants operate with PWM interface control, requiring a supply voltage of 0V to 5.3V. These parts support two half-bridge outputs and are suitable for applications where PWM-based speed and direction control is implemented.

The DRV8436RGER variant operates with Step/Direction interface control, supporting supply voltage of 0V to 5.5V and two half-bridge outputs. This part includes step resolution capability of greater than 256 microsteps, making it suitable for stepper motor applications requiring microstepping functionality.

Package differences between the 28-PowerTSSOP (DRV8812PWPR) and 24-VFQFN (DRV8436 variants) require PCB layout redesign and footprint modification. Operating temperature ranges differ, with the DRV8812PWPR supporting junction temperatures to 150°C compared to 125°C ambient for the DRV8436 variants.

Frequently Asked Questions (FAQ)

Q: Can DRV8436 variants directly replace DRV8812PWPR without circuit modification?

A: No. The DRV8436 variants differ in interface protocol (PWM or Step/Direction versus Parallel), output configuration (2 versus 4 half-bridges), supply voltage range (0V-5.3V/5.5V versus 8.2V-45V), and package form factor (24-VQFN versus 28-PowerTSSOP). Circuit redesign is required.

Q: What is the primary difference between DRV8436ERGER, DRV8436PRGER, and DRV8436RGER?

A: The primary difference is interface protocol. DRV8436ERGER and DRV8436PRGER use PWM interface control. DRV8436RGER uses Step/Direction interface control with microstepping capability (>256 microsteps). All three share identical electrical specifications for current, voltage, and temperature ratings.

Q: Are package changes between DRV8812PWPR and DRV8436 variants compatible with existing PCB layouts?

A: No. The DRV8812PWPR uses 28-PowerTSSOP packaging while DRV8436 variants use 24-VFQFN Exposed Pad packaging. PCB footprint redesign is required.

Q: What supply voltage considerations apply when selecting between these parts?

A: The DRV8812PWPR operates from 8.2V to 45V supply voltage. DRV8436ERGER and DRV8436PRGER operate from 0V to 5.3V supply voltage. DRV8436RGER operates from 0V to 5.5V supply voltage. Load voltage ranges differ as well. Application supply voltage requirements determine part selection.

Q: Do all parts support both stepper and brushed DC motor applications?

A: Yes. All parts listed support both bipolar stepper motor and brushed DC motor applications through their fully integrated driver architecture.

Q: What is the output current difference between DRV8812PWPR and DRV8436 variants?

A: DRV8812PWPR provides 1.6A output current. DRV8436 variants (ERGER, PRGER, RGER) provide 1.5A output current. This 0.1A difference may impact motor selection in current-limited applications.
