Product details
Overview
DRV8810PAP from Texas Instruments is a highly integrated combination motor driver IC with three programmable DC-DC buck converters, four H-bridge outputs, and dual 16-bit serial interfaces. It delivers 1.5-A continuous DC-DC output current, supports 800-mA average stepper motor drive per bridge, operates from 7-V to 40-V VDIN, and implements 16-step current-mode microstepping control for bipolar stepper motors in a thermally enhanced 64-pin QFP PowerPAD™ package - used in industrial automation motion controllers requiring compact multi-motor power management.
For engineers reviewing the DRV8810PAP datasheet, DRV8810PAP pinout, DRV8810PAP application, or DRV8810PAP equivalent, this page provides verified technical context on its configurable motor-driver modes (dual stepper, stepper + dual DC, quad DC), DC-DC converter selection logic via C_SELECT, thermal shutdown thresholds, and SPI-compatible serial interface timing - all critical for embedded motion system design, BOM validation, and layout-aware fault handling.
Technical Context
The DRV8810PAP integrates four N-channel H-bridges with programmable blanking time (3.75–7.5 μs), 16-step current-mode microstepping, and independent A/B and C/D serial interfaces supporting 25-MHz clock rates. Its three DC-DC converters are independently configurable: Channel A outputs 1.5 V to 80% of VDIN (max 30 V), while Channels B and C deliver up to 10 V each - selectable at startup via C_SELECT or dynamically via serial interface.
Internal protection includes overcurrent detection (1.8–3 A per ODx), undervoltage/overvoltage lockout (±30% VFB threshold), thermal shutdown (150–190°C), and pre-TSD analog temperature sensing (6 mV/°C at TH_OUT). The device supports eight motor configuration modes - including ultra-large DC and large stepper - controlled by setup register bits accessible only during nSLEEP = L initialization.

Pinout & Package
DRV8810PAP uses a thermally enhanced 64-pin plastic QFP PowerPAD™ package (PAP) with exposed thermal pad for improved heat dissipation in high-power motor drive applications. Pin numbering follows standard top-view orientation with Pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA+, OUTA− | Stepper/DC motor winding A terminals | Full H-bridge outputs driving one phase of bipolar stepper or DC motor; require external flyback diodes or snubbers |
| RSA | Current-sense resistor connection (Channel A) | Connects to low-side sense resistor (typically 0.1 Ω) for closed-loop current regulation and overcurrent protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar combination motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8809PAP | Identical pinout, register map, and electrical specs; differs only in factory-programmed default motor configuration (DRV8809 = dual stepper; DRV8810 = stepper + dual DC) | Requires identical PCB layout but different setup register initialization sequence to achieve same functional mode | Select DRV8809PAP if dual-stepper default behavior aligns with system boot requirements; no hardware change needed |
| TB9051FTG | Single H-bridge + integrated 1.2-A buck; lacks multi-bridge flexibility, serial interface, and programmable DC-DC outputs | Only suitable for single-axis DC motor control; cannot replicate DRV8810PAP's dual-stepper or quad-DC capability | Choose TB9051FTG only for cost-sensitive single-motor applications where integration density is secondary to unit price |
Compared with DRV8809PAP, the DRV8810PAP offers identical hardware but optimized factory defaults for stepper-plus-DC use cases - reducing firmware initialization overhead. Against TB9051FTG, it delivers 4× motor drive channels and 3× DC-DC converters in one die, enabling system-level consolidation unattainable with single-channel alternatives.

FAQ
What motor configurations does the DRV8810PAP support?
The DRV8810PAP supports eight distinct motor configurations via its setup register, including dual stepper, stepper + large DC, stepper + dual small DC, dual large DC, quad small DC, large stepper, and ultra-large DC. Each mode determines how the four H-bridges (OUTA± through OUTD±) and three DC-DC converters are allocated - for example, "stepper + dual small DC" assigns OUTA±/OUTB± to a bipolar stepper and OUTC±/OUTD± to independent DC motors. Configuration is set during nSLEEP = L initialization using the 3-bit MOTOR_SELECT field in the setup register. DRV8810PAP's flexibility eliminates the need for multiple discrete drivers in complex multi-axis systems.
How does the C_SELECT pin determine DC-DC converter startup behavior on the DRV8810PAP?
The C_SELECT pin on the DRV8810PAP selects the initial DC-DC converter activation sequence at power-up based on its voltage level and the state of DCDC_MODE. With DCDC_MODE = L, a grounded C_SELECT (≤0.3 V) disables all converters; a 200-kΩ pull-down yields 1.3–2.0 V, enabling ODA then ODB/ODC; an open C_SELECT (≥3.0 V) enables ODB/ODC then ODA. With DCDC_MODE = H or open, the same voltages configure Ch-B/C in parallel mode. This hardware-selectable startup logic allows deterministic power sequencing without firmware intervention - critical for systems where DC-DC rail ordering affects downstream logic stability. DRV8810PAP's C_SELECT behavior is fully documented in Table 1 of the SLVS854D datasheet.
What is the purpose of the TH_OUT pin on the DRV8810PAP, and how is it used?
The TH_OUT pin on the DRV8810PAP provides an analog voltage output proportional to die temperature (6 mV/°C), enabling pre-thermal-shutdown monitoring. Unlike the digital nORT signal that asserts only during hard thermal shutdown (TTSD = 150–190°C), TH_OUT allows firmware to read real-time junction temperature and implement predictive thermal throttling - for example, reducing motor current when TH_OUT indicates 140°C to avoid triggering TSD. The output is linear and referenced to LGND, requiring a simple ADC input on the host MCU. This feature is especially valuable in sealed enclosures or high-ambient environments where passive cooling is limited. DRV8810PAP's TH_OUT is active in all operating modes, including deep-sleep.
Can the DRV8810PAP be used for microstepping, and what resolution does it support?
Yes, the DRV8810PAP supports true 16-step current-mode microstepping for bipolar stepper motors using its integrated current regulation architecture. It achieves this by digitally controlling the reference voltage applied to the current-sense amplifiers (VREF_AB/VREF_CD) and modulating H-bridge duty cycles via internal PWM chopping at 90–110 kHz. The 16-step profile is fixed and non-interpolated - meaning each step corresponds to a discrete current vector angle (0° to 90° in 6° increments), delivering smoother motion and reduced resonance compared to full/half-step modes. DRV8810PAP's microstepping is implemented entirely in hardware, requiring no host MCU computation; the step sequence is advanced automatically upon receiving serial commands via DATA_AB/STROBE_AB.
What protection features are integrated into the DRV8810PAP, and how do they behave during fault conditions?
The DRV8810PAP integrates comprehensive protection: overcurrent (1.8–3 A per ODx channel), overvoltage/undervoltage lockout (±30% VFB threshold), thermal shutdown (150–190°C), and VM supervision (nORT assertion at VM < 4.5 V). Upon fault detection, it asserts nORT (open-drain) and places all H-bridge outputs in high-impedance state within microseconds. Crucially, it also provides programmable pre-TSD alerts via TH_OUT and fault-status visibility through LOGIC_OUT in extended setup mode - allowing firmware to log root cause (e.g., "OCP on OUTC−") before shutdown. All protections are hardware-based with filtering (e.g., 2–8.5 μs deglitching) to prevent false triggers from transient noise. DRV8810PAP's layered fault response ensures system safety without requiring external monitoring circuitry.
