Product details
Overview
DRV8245SQPWPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive H-bridge driver supporting 4.5V–35V operation, 32A peak output current, and integrated high-side current sensing with proportional IPROPI analog feedback. It operates in single full-bridge or dual half-bridge mode, features configurable slew rate (up to 50 V/µs), spread-spectrum clocking, and supports 3.3V/5V logic inputs for body control modules and seat actuation systems.
For engineers reviewing the DRV8245SQPWPRQ1 datasheet, DRV8245SQPWPRQ1 pinout, DRV8245SQPWPRQ1 application, or DRV8245SQPWPRQ1 equivalent, this page delivers verified package mapping (HTSSOP-28), confirmed SPI(P) variant functionality, validated fault diagnostics (open-load, short-circuit, overcurrent, overtemperature), and real-world design values including RON(HS+LS) = 40 mΩ and sleep current = 1 µA at 25°C.
Technical Context
The DRV8245SQPWPRQ1 implements a monolithic BiCMOS N-channel H-bridge with integrated charge pump, high-side current regulation, and configurable fault reaction (latched or retry). Its SPI(P) interface uses externally supplied 4.5–5.5V VDD logic power, eliminating brownout during VM transients and enabling precise register-level control of ITRIP thresholds, dead time, and diagnostic reporting.
It supports three bridge control modes: PWM, PH/EN, and Independent half-bridge - with Hi-Z capability per half-bridge only in SPI variants. Load diagnostics operate in both on-state (high-side active) and off-state, and voltage monitoring covers VM supply with four programmable overvoltage thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.5V to 35V VM; absolute max 40V - supports 12V/24V automotive battery systems with transient tolerance. |
| Output Current | 32A peak (IOUT(MAX)) - enables direct drive of high-power brushed DC motors in door/trunk modules. |
| RON(HS+LS) | 40 mΩ (HTSSOP package) - reduces conduction loss and thermal stress at full load in compact layouts. |
| PWM Frequency | Up to 25 kHz with automatic dead-time assertion - ensures clean commutation without external timing circuitry. |
| Sleep Current | 1 µA typical at 25°C - meets ultra-low quiescent power requirements for always-on automotive ECUs. |
| Logic Interface | SPI(P) variant with external 4.5–5.5V VDD - decouples logic supply from VM, preventing reset during battery dips. |
| Fault Reporting | nFAULT open-drain output + register-based logging - provides both immediate system alert and post-fault root-cause analysis. |
Pinout & Package
DRV8245SQPWPRQ1 is packaged in HTSSOP-28 (4.4 mm × 9.7 mm) with exposed thermal pad. Pin functions are defined for the SPI(P) variant, where VDD supplies logic independently from VM.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VM (Pins 6,7,8,21,22,23) | Motor power supply input | Must be bypassed with 0.1 µF ceramic + bulk capacitor; six parallel pins support high-current routing and thermal dissipation. |
| OUT1 (Pins 9,10,11) / OUT2 (Pins 18,19,20) | H-bridge output terminals | Each group connects to motor terminals; paralleling pins lowers effective RDS(on) and improves current sharing. |
| VDD (Pin 24) | External logic supply input | Accepts 4.5–5.5V; isolates digital core from VM fluctuations - critical for robust SPI communication during cranking. |
| SDI, SDO, SCLK, nSCS (Pins 28,27,1,2) | SPI interface signals | Full-duplex 4-wire interface with internal pull-up/pull-down resistors; supports daisy-chaining in multi-driver systems. |
| nFAULT (Pin 26) | Open-drain fault indicator | Asserts low on overcurrent, overtemperature, open-load, or short-circuit; can drive microcontroller interrupt directly. |
| IPROPI (Pin 25) | Analog current sense output | Proportional to load current (±10% accuracy); eliminates external shunt resistor and associated PCB area/power loss. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated high-side current sense | Eliminates external shunt resistor and associated layout complexity, measurement error, and power loss - enables accurate closed-loop current regulation. |
| Configurable slew rate (8 levels) | Reduces EMI emissions by controlling edge rates (1.5–50 V/µs); selectable per application noise constraints without hardware change. |
| SPI(P) logic supply independence | VDD pin accepts dedicated 4.5–5.5V source, preventing device reset during VM under-voltage transients - essential for safety-critical body control modules. |
| On-state and off-state load diagnostics | Detects open-load and short-to-battery/ground faults regardless of H-bridge state - improves functional safety compliance and system reliability. |
| Programmable ITRIP regulation | 7 current-limit threshold levels with programmable TOFF time - allows fine-tuned trade-off between motor torque, thermal margin, and fault response speed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8244QPWPRQ1 | RON(HS+LS) = 60 mΩ (HTSSOP); 21A peak output; supports same SPI(P) interface and diagnostics. | Lower current capability suits smaller loads (e.g., mirror actuators) but requires derating for 32A-class motors. | Select when thermal budget or cost constraints permit higher conduction loss and reduced peak current headroom. |
| DRV8245HQPWPRQ1 | HW (hardwired) interface variant; no SPI, no VDD pin; fixed slew rate (6 levels), no register-based diagnostics. | Lacks programmable fault logging and independent half-bridge Hi-Z - suitable for simpler, cost-sensitive designs without advanced diagnostics. | Choose for non-safety-critical applications where firmware overhead and diagnostic depth are not required. |
Compared with DRV8244QPWPRQ1 and DRV8245HQPWPRQ1, the DRV8245SQPWPRQ1 delivers highest current drive (32A), lowest RON (40 mΩ), and most flexible configuration via SPI(P), making it optimal for ASIL-B-compliant systems demanding precise current control and comprehensive fault observability.

FAQ
What is the function of the VDD pin on the DRV8245SQPWPRQ1?
The VDD pin on the DRV8245SQPWPRQ1 supplies dedicated 4.5–5.5V power to the device's logic core and SPI interface. Unlike the VM supply, VDD remains stable during battery transients, preventing brownout resets and ensuring reliable register access and fault reporting - a key differentiator of the SPI(P) variant over SPI(S) or HW versions.
Does the DRV8245SQPWPRQ1 support both full-bridge and dual half-bridge configurations?
Yes, the DRV8245SQPWPRQ1 supports both configurations via MODE pin or SPI register setting. In full-bridge mode, it drives a single brushed DC motor bidirectionally. In Independent mode, it controls two separate loads - such as seat fore/aft and recline motors - with individual enable, direction, and current regulation per half-bridge.
How does the integrated current sense work on the DRV8245SQPWPRQ1?
The DRV8245SQPWPRQ1 uses high-side current sensing with proportional analog output on the IPROPI pin. The output voltage scales linearly with load current (e.g., 1V/A typical), enabling direct ADC sampling without external shunts. This architecture avoids ground path disruption and maintains accuracy across wide temperature ranges (-40°C to +125°C).
What fault conditions does the DRV8245SQPWPRQ1 detect and report?
The DRV8245SQPWPRQ1 detects and reports overcurrent, overtemperature, VM undervoltage/overvoltage, open-load (in on/off states), and short-to-battery/ground faults. Faults trigger the nFAULT pin and are logged in SPI-accessible registers - allowing host MCUs to distinguish between transient events and persistent failures for appropriate system response.
Is the DRV8245SQPWPRQ1 pin-compatible with other devices in the DRV824x-Q1 family?
No - the DRV8245SQPWPRQ1 is not pin-compatible with DRV8243Q1 or DRV8244Q1 due to differing pin counts (HTSSOP-28 vs. HVSSOP-28) and signal assignments (e.g., VDD replaces nSLEEP in SPI(P) variant). While functional overlap exists, PCB redesign is required for substitution; refer to TI's Device Comparison Table for exact mappings.
