Product details
Overview
DRV8808DCA from Texas Instruments is a 48-pin HTSSOP integrated motor driver IC for multi-motor systems, featuring three independent full H-bridge drivers (2.5-A peak per channel), three programmable buck DC-DC converters (1.35-A output, 1 V to 90% of VM), and one configurable LDO regulator (550-mA, 1–2.5 V). It delivers coordinated motion control in printer carriage, paper feed, and scanner actuator subsystems.
For engineers reviewing the DRV8808DCA datasheet, DRV8808DCA pinout, DRV8808DCA application, or DRV8808DCA equivalent, key selection considerations include its triple-H-bridge topology with internal/external current sensing, serial SPI interface (3.3-V compatible, 5-V tolerant), thermal warning (TH_OUT), reset signaling (nORT), and deep-sleep power-down mode (1-mA typical).
Technical Context
The DRV8808DCA integrates three independent motor drive channels-each with N-channel MOSFET H-bridges, programmable current chopping (90–200 kHz), and configurable blanking/tblank timing-alongside three synchronous buck converters sharing a common VM input but individually adjustable via FB_A/FB_B/FB_C feedback networks. All DC-DC outputs support external resistor programming from 1 V to 90% of VM.
Its serial interface uses STROBE/CLK/DATA with nSLEEP-gated register access, enabling runtime configuration of motor parameters (chop frequency, Tblank, MISD blank) and regulator enable states. Internal protection includes overcurrent detection per H-bridge (3–8 A threshold), VM undervoltage lockout (VthVM− = 5 V typ), thermal shutdown (170°C), and pre-TSD warning (135°C).
Key Specifications

Pinout & Package
DRV8808DCA is housed in a thermally enhanced 48-pin HTSSOP (DCA) package with exposed PowerPAD™ for improved heat dissipation. Pin functions are validated per TI SLVS857B datasheet Rev. January 2015.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A+, A− | H-bridge motor output pair for Channel A | Drive brushed DC motor winding A; supports bidirectional current flow and PWM-controlled current chopping. |
| B+, B− | H-bridge motor output pair for Channel B | Drive brushed DC motor winding B; electrically isolated from Channel A/B/C for independent control. |
| C+, C− | H-bridge motor output pair for Channel C | Drive brushed DC motor winding C; enables three-axis motion control in multi-motor applications like document scanners. |
| OD_A, OD_B, OD_C | DC-DC converter switch node outputs | Connect to external inductor-capacitor filter networks; each regulates independent output voltage via respective FB_x pin. |
| FB_A, FB_B, FB_C | DC-DC feedback inputs | Set output voltage via external resistor divider; precision 1-V reference enables ±3% regulation accuracy across temperature. |
| nORT | Open-drain reset output | Asserts low during VM undervoltage, thermal shutdown, or overcurrent; synchronizes system-level fault recovery. |
| TH_OUT | Open-drain temperature warning | Signals pre-shutdown condition at 135°C; allows firmware to reduce load or initiate cooling before nORT triggers. |
| nSLEEP / nWAKEUP | Deep-sleep enable and wake-up inputs | Enable ultra-low-power state (1-mA supply current); nWAKEUP provides asynchronous wake-up without VM cycling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-channel motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8816PWP | Two H-bridges only; no integrated DC-DC converters or LDO; 2-A peak per channel; 32-pin HTSSOP. | Requires external buck regulators for logic rails; suitable for dual-motor systems with simpler power architecture. | Select when only two motor channels are needed and board space permits discrete regulators. |
| MP6532DS-LF-Z | Three H-bridges (2.8-A peak); no integrated DC-DC or LDO; 40-V max VM; QFN-48 package; I²C interface. | Lacks on-chip voltage regulation-requires separate 3.3-V/1.8-V supplies; uses I²C instead of SPI. | Choose for higher peak current and QFN thermal performance where external regulators are already present. |
Compared with DRV8816PWP and MP6532DS-LF-Z, the DRV8808DCA uniquely combines triple motor drive, three buck converters, and an LDO in one HTSSOP package-reducing total solution size by ≥35% and eliminating six external regulators in printer-class designs.

FAQ
What is the maximum continuous current per H-bridge channel in DRV8808DCA?
The DRV8808DCA supports 2.5-A continuous motor drive current per H-bridge channel (A, B, or C) under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). Peak current capability reaches 6.8 A for sub-500-ns pulses, enabling robust start-up torque for high-inertia loads in printer mechanisms.
How does the DRV8808DCA configure its DC-DC converter output voltages?
The DRV8808DCA sets each DC-DC output voltage (OD_A, OD_B, OD_C) via external resistor dividers connected to FB_A, FB_B, and FB_C pins. With a precise 1-V internal reference, output voltage is calculated as VOUT = 1 V × (1 + Rtop/Rbottom). This enables accurate, temperature-stable regulation from 1 V to 90% of VM without trimming.
Does DRV8808DCA support both internal and external current sensing for motor windings?
Yes, the DRV8808DCA supports configurable current sensing: internal sensing uses integrated MOSFET RDS(on) measurement (RDSON = 0.55 Ω typ at 70°C), while external sensing connects shunt resistors to RSA/RSKA, RSB/RSKB, or RSC/RSKC pins. Configuration is controlled via VRS_A/B/C bits in the Extended Setup Register.
What protection features are integrated into DRV8808DCA?
The DRV8808DCA integrates per-channel overcurrent detection (3–8 A threshold), VM undervoltage lockout (VthVM− = 5 V), thermal shutdown (170°C), pre-TSD warning (135°C on TH_OUT), and short-circuit protection. All faults assert nORT to coordinate system-level response, and deep-sleep mode reduces supply current to 1 mA during idle periods.
Can DRV8808DCA operate with a 5-V logic interface despite its 7–40-V VM range?
Yes, the DRV8808DCA's SPI interface (STROBE, CLK, DATA) and digital control pins (nSLEEP, nReset, CSELECT) are 3.3-V compatible and 5-V tolerant. This allows direct connection to 3.3-V or 5-V microcontrollers without level shifters-simplifying host interface design while maintaining full functionality across the 7–40-V VM operating range.
