Shenzhen Mingjiada Electronics Co., Ltd. specialises in the long-term supply and buy-back of original Texas Instruments DRV8242 automotive H-bridge drivers, providing stable and efficient component supply and stock buy-back services to automotive electronics manufacturers worldwide.
Product Overview
The DRV8242 is an automotive-grade H-bridge driver from Texas Instruments’ DRV824x-Q1 series. It is certified to the AEC-Q100 standard (Temperature Grade 1: –40°C to +125°C) and is specifically designed for a wide range of automotive applications. Manufactured using BiCMOS high-power process technology, this device delivers outstanding power handling and thermal performance within a compact power package, whilst offering multiple advantages including a small footprint, EMI control and precise current sensing.
Key Technical Features
Wide operating voltage range: The DRV8242 supports an operating voltage range of 4.5 V to 35 V (absolute maximum of 40 V), making it ideal for 12 V automotive system applications.
High output current capability: With a maximum output current of 6 A in a QFN package and an on-resistance (RON_LS + RON_HS) of just 250 mΩ, it effectively reduces power consumption in high-current scenarios.
Integrated current sensing: The DRV8242 features built-in high-side current sensing, eliminating the need for external shunt resistors. It outputs a proportional load current via the IPROPI pin, significantly simplifying system design and saving PCB space.
Flexible control interfaces: Three control interface variants are available—HW (hard-wired interface), SPI (S) and SPI (P). The SPI interface variants offer greater flexibility in device configuration and fault observability.
Low EMI design: Configurable slew rate and spread-spectrum clocking technologies effectively reduce electromagnetic interference, meeting the stringent EMC requirements of automotive electronics.
Comprehensive protection and diagnostics: Integrated overcurrent protection (OCP), thermal shutdown (TSD), supply voltage monitoring (VM), open-load and short-circuit detection functions; fault conditions are indicated via the nFAULT pin, with support for both latch and retry fault response modes.
Ultra-low sleep current: A typical sleep current of just 1.3 μA at 25°C helps reduce the vehicle’s overall static power consumption.
Typical Automotive Applications
As a fully integrated bidirectional full-bridge driver, the DRV8242 supports PWM or phase-enable (PH/EN) control modes and can be configured as a single H-bridge driver or two independent half-bridge drivers. Its primary automotive applications include:
Automotive brushed DC motor drives: door modules, seat adjustment modules, sunroof control, tailgate control, etc.
Body Control Module (BCM): Drive for various body electronic actuators
Solenoid valve drive: Gas engine systems, transmission solenoid valve control
On-board charger: Motor and actuator drive in OBC systems
This device integrates an N-channel H-bridge, a charge pump regulator, high-side current detection and regulation circuits, and protection circuits, providing a highly integrated, one-stop solution for automotive motor drives.
