Product details
Overview
DRV8806PWP from Texas Instruments is a quad-channel protected low-side NMOS driver IC with serial interface control, integrated clamp diodes, overcurrent/thermal/UVLO protection, and 1-A continuous per-channel drive capability (all channels active) at 25°C on standard PCBs. It drives unipolar stepper motors, relays, solenoids, or inductive DC loads in industrial motion control systems.
For engineers reviewing the DRV8806PWP datasheet, DRV8806PWP pinout, DRV8806PWP application, or DRV8806PWP equivalent, key selection considerations include its 8.2–40 V operating range, HTSSOP-16 thermal performance (RθJA = 39.6°C/W), 500 mΩ typical RDS(ON) at 25°C, open-load detection via 25-µA current source, and daisy-chainable 1-MHz serial interface with push-pull SDATOUT.
Technical Context
The DRV8806PWP implements four independent low-side gate drivers with analog overcurrent limiting (3–5 A trip level, 3.5 µs deglitch), thermal shutdown at ~150°C, and undervoltage lockout at 8.2 V. Each channel features an integrated clamp diode connected to the VCLAMP pin, configurable to VM or a Zener/TVS for fast inductive decay.
Its serial interface uses SCLK/SDATIN/LATCH with push-pull SDATOUT (1 mA source / 5 mA sink), enabling daisy-chaining of multiple devices. Fault status (OCP, open-load, overtemperature) is reported via nFAULT (open-drain) and readable through the serial shift register after LATCH assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8.2 V to 40 V - supports wide industrial motor supply rails without external regulation |
| Continuous Output Current | 1 A per channel (all four active) - defines maximum sustained load drive under thermal limits on FR-4 PCB |
| RDS(ON) (Typical) | 500 mΩ at VM = 24 V, TJ = 25°C - determines I²R conduction loss and thermal rise per channel |
| Overcurrent Trip Level | 3–5 A - sets analog current limit threshold before fault shutdown and retry cycle (1.2 ms) |
| Serial Interface Speed | Up to 1 MHz - enables fast configuration and fault readback without external pullup resistor |
| Open-Load Detection | 25 µA current source + 1.2 V threshold - reliably identifies disconnected loads during off-state with 15 µs deglitch |
| Thermal Shutdown | 150–180°C die temperature - disables all outputs until safe junction temperature is restored |
Pinout & Package
DRV8806PWP is housed in a thermally enhanced 16-pin HTSSOP package (5.00 mm × 4.40 mm) with exposed PowerPAD™ for PCB-level heat dissipation. The package is RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VM (Pin 1) | Motor power supply input | Primary high-voltage rail (8.2–40 V); powers internal gate drivers and logic regulators |
| VCLAMP (Pin 2) | Clamp diode common node | Connects to VM or Zener/TVS to manage inductive flyback energy and enable fast current decay |
| OUT1–OUT4 (Pins 3,4,6,7) | Low-side NMOS output terminals | Four independent sinking outputs; each rated for 2-A peak, 1-A continuous (all on) |
| GND (Pins 5,12,16) | Ground reference | Three dedicated ground pins plus PowerPAD™ - minimize ground impedance and improve thermal path |
| SCLK, SDATIN, LATCH, RESET, nENBL (Pins 13–11,9,8) | Serial control and enable inputs | All have internal pulldowns; support daisy-chain configuration and fault-safe default-off behavior |
| SDATOUT (Pin 15) | Serial data output | Push-pull driver (1 mA source / 5 mA sink) - eliminates need for external pullup up to 1 MHz |
| nFAULT (Pin 16) | Fault status indicator | Open-drain output pulled low on OCP, open-load, or overtemperature - shared across all channels |
Key Features
| Feature | Design Value |
|---|---|
| Integrated clamp diodes | Eliminates need for external flyback diodes; VCLAMP pin allows flexible clamping to VM or Zener for optimized decay time |
| Daisy-chain serial interface | Single SCLK/SDATIN/LATCH bus controls multiple DRV8806PWP devices - reduces MCU GPIO count and simplifies firmware |
| Per-channel open-load detection | 25-µA current source + voltage sensing detects disconnected loads during off-state - critical for relay/solenoid health monitoring |
| Auto-retry overcurrent protection | 3.5 µs deglitch + 1.2 ms retry cycle - recovers automatically after transient overload without MCU intervention |
| Thermally enhanced HTSSOP | PowerPAD™ and low RθJA (39.6°C/W) enable 1-A continuous operation on standard 2-layer FR-4 without heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TBD7200AFG,EL | 8-channel, 1.5-A continuous, 5.5–28 V supply, SPI interface, no integrated clamp diodes | Higher channel count but narrower voltage range; requires external flyback diodes | Preferred when higher channel density and SPI compatibility are needed, and board space permits external diodes |
| TPIC2603DWR | Quad low-side driver, 1.5-A continuous, 5.5–36 V, parallel control (no serial interface), open-drain outputs | Lacks serial interface and integrated clamp diodes; simpler control but less diagnostic capability | Selected for cost-sensitive designs where daisy-chaining and fault readback are unnecessary |
Compared with TBD7200AFG,EL and TPIC2603DWR, the DRV8806PWP uniquely combines serial daisy-chaining, integrated clamp diodes, and open-load detection in a single 16-pin HTSSOP - making it optimal for space-constrained, diagnostics-aware industrial motion systems requiring 8.2–40 V operation.

FAQ
What is the maximum continuous output current per channel for DRV8806PWP?
The DRV8806PWP supports 1 A continuous output current per channel when all four channels are active at TA = 25°C on a standard FR-4 PCB with adequate copper area. With only one channel active, it delivers up to 2 A continuously. This rating assumes proper thermal management via the PowerPAD™ and PCB layout per TI's layout guidelines.
Does DRV8806PWP require external flyback diodes when driving inductive loads?
No, the DRV8806PWP integrates clamp diodes for each output channel, connected to the VCLAMP pin. When VCLAMP is tied to VM, these diodes provide standard flyback protection. For faster current decay (e.g., in stepper motor applications), VCLAMP can be connected to a Zener or TVS diode referenced to VM - eliminating the need for discrete external diodes.
How does the serial interface of DRV8806PWP support daisy-chaining?
The DRV8806PWP's serial interface supports daisy-chaining via its push-pull SDATOUT pin (capable of 1 mA source / 5 mA sink), which directly drives the SDATIN pin of the next device. SCLK, LATCH, RESET, and nFAULT are shared across all devices. Data is shifted in and out sequentially, allowing one MCU interface to configure and monitor multiple DRV8806PWP ICs with minimal GPIO usage.
What fault conditions trigger the nFAULT pin on DRV8806PWP?
The nFAULT pin on DRV8806PWP is driven low (active) during overcurrent (OCP), open-load, or overtemperature (TSD) events on any channel. It remains low until the fault condition clears - either automatically after thermal recovery or OCP retry timeout, or manually via RESET assertion or VM cycling. The fault status per channel is also readable via the serial interface.
What is the purpose of the VCLAMP pin on DRV8806PWP?
The VCLAMP pin on DRV8806PWP serves as the common anode connection point for all four integrated clamp diodes. It must be connected - typically to VM for standard flyback clamping, or to a Zener/TVS diode referenced to VM - to safely dissipate inductive energy during output turn-off. Proper VCLAMP routing is essential for managing voltage transients and optimizing current decay time in stepper or solenoid applications.
