Product details
Overview
DRV8809PAP from Texas Instruments is a highly integrated combination motor driver IC featuring four independent H-bridge power stages and three programmable DC-DC buck converters. It delivers 800-mA average stepper current per bridge, supports 16-step current-mode microstepping via SPI, and provides up to 1.5-A output per DC-DC channel (3-A in B/C parallel mode) across a 7–40-V input range. It is used in multi-axis printer carriage control where precise bipolar stepper positioning and on-board logic rail generation are required.
For engineers reviewing the DRV8809PAP datasheet, DRV8809PAP pinout, DRV8809PAP application, or DRV8809PAP equivalent, key selection criteria include its dual serial interfaces (AB/CD), configurable motor drive modes (dual stepper, stepper + quad DC, large DC), thermal shutdown at 150°C, and 64-pin HTQFP package with PowerPAD™ for enhanced thermal performance.
Technical Context
The DRV8809PAP integrates four N-channel H-bridges with 0.55-Ω typical RDS(ON) at 25°C, enabling 800-mA continuous and 3-A/100-ms peak motor current per channel. Its three independent DC-DC converters support programmable outputs: Channel A (1.5–VDIN×0.8), Channels B/C (1.5–10 V), selectable via C_SELECT or SPI.
Motor control uses a 16-step current-mode architecture synchronized to an internal 800-kHz oscillator (fchop = 100 kHz), while DC-DC regulation employs fixed-frequency PWM at 90–110 kHz. Protection includes overcurrent detection (1.8–3 A per ODx), UVLO (VM thresholds at 5 V ±1 V), and thermal shutdown with pre-TSD analog temperature sensing (6 mV/°C).

Equivalent & Alternatives
The following parts are listed as comparable options for similar combination motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8810PAP | Same pinout and feature set, but supports higher peak current (8 A/500 ns vs 3 A/100 ms) and adds dedicated large DC motor mode with 5-A capability | Better suited for high-inertia copier drum drives requiring >3-A sustained current | Select DRV8810PAP when peak motor current exceeds 3 A or large DC motor control is primary use case |
| BD63001MUV | Single 4-H-bridge stepper+DC driver with integrated DC-DC, but only one serial interface and no B/C parallel DC-DC mode | Limited to single-axis or simpler dual-motor systems without independent AB/CD control | Choose BD63001MUV for cost-sensitive, lower-complexity scanners where dual SPI interfaces are unnecessary |
Compared with DRV8810PAP, the DRV8809PAP offers identical integration and package but trades peak current headroom for tighter thermal budgeting; versus BD63001MUV, it delivers superior multi-axis coordination and flexible DC-DC configuration at higher system-level design complexity.

FAQ
What motor configurations does the DRV8809PAP support?
The DRV8809PAP supports eight configurable modes including dual bipolar stepper, stepper + quad DC, large DC + dual small DC, and ultra-large DC. Each mode is selected via pin strapping (C_SELECT, DCDC_MODE) or SPI register writes. The DRV8809PAP's four H-bridges can be grouped as AB/CD pairs or operated individually, enabling flexible axis allocation in multi-motor systems like printers and scanners.
How does the DRV8809PAP implement current regulation for stepper motors?
The DRV8809PAP uses 16-step current-mode control with external sense resistors (RSA–RSD) and analog reference inputs (VREF_AB/VREF_CD). Current is regulated by comparing the sense resistor voltage against a DAC-generated ramp waveform synchronized to the internal 800-kHz oscillator. This enables precise microstepping with 800-mA average current per bridge and 1.3-A peak capability, as confirmed in the datasheet's electrical characteristics table.
Can the three DC-DC converters on the DRV8809PAP operate simultaneously?
Yes - all three DC-DC converters (Ch-A, Ch-B, Ch-C) can operate concurrently. Channel A is independently programmable from 1.5 V to 80% of VDIN, while Channels B and C support 1.5–10 V outputs and may be configured in parallel mode (via DCDC_MODE = H) to deliver up to 3-A total. Startup sequencing is controlled by C_SELECT voltage level and internal soft-start timers (56-ms duration), ensuring stable rail establishment before motor activation.
What thermal management features does the DRV8809PAP provide?
The DRV8809PAP includes thermal shutdown at 150°C (TTSD), register-selectable pre-TSD warning thresholds (120–170°C), and an analog TH_OUT output with 6 mV/°C temperature coefficient. Its 64-pin HTQFP package features an exposed PowerPAD™ thermal pad that achieves RθJA = 26.2°C/W with standard 2-oz copper PCB layout. These features allow predictive thermal derating and system-level cooling coordination without external sensors.
Is the DRV8809PAP pin-compatible with any other TI motor drivers?
Yes - the DRV8809PAP shares identical pinout, package (HTQFP-64), and functional register map with the DRV8810PAP. Both devices support the same eight motor drive modes and dual serial interfaces. Key differences lie in current capability: DRV8810PAP supports 8-A/500-ns peak current per H-bridge versus 3-A/100-ms for DRV8809PAP, making DRV8810PAP suitable for higher-inertia loads while maintaining drop-in compatibility in most designs.
