The DRV8343SPHPRQ1 is an AEC‑Q100 Grade 1 qualified three‑phase smart gate driver manufactured by Texas Instruments, designed for 12 V and 24 V automotive systems with 5.5 V to 50 V continuous supply and 60 V transient voltage tolerance. Packaged in 48‑pin HTQFP‑PHP with exposed thermal pad, this SPI‑controlled unit drives six external N‑channel MOSFETs for BLDC, brushed‑DC and solenoid loads, integrating three configurable current‑sense amplifiers, built‑in charge pump for 100% duty‑cycle operation, abundant diagnostic and protective circuits, and an internal 3.3 V LDO to simplify automotive ECU hardware layout and reduce peripheral component count.
Key highlights
● AEC‑Q100 Grade 1 automotive qualification supporting ‑40 ℃ to 125 ℃ ambient working temperature
● Smart gate drive with adjustable peak source (1.5 mA‑1 A) and sink (3 mA‑2 A) currents for MOSFET slew‑rate tuning without external gate resistors
● Three integrated current‑sense amplifiers offering four selectable gain levels (5,10,20,40 V/V) for bidirectional phase‑current monitoring
● Flexible SPI‑based configuration supporting multiple PWM modes and independent half‑bridge control for multi‑load actuation
● Comprehensive on‑chip protections covering UVLO, over‑temperature, VDS MOSFET fault, shoot‑through prevention and open‑gate detection with fault reporting via SPI interface
● Embedded charge pump enabling full 100% PWM duty‑cycle and optional reverse‑protection MOSFET driving, plus a 3.3 V, 30 mA linear regulator for auxiliary circuit power supply.
Common questions
Q: Can DRV8343SPHPRQ1 work without external current‑sense resistors?
A: It still needs external shunt resistors for CSA input, while internal amplifiers process sensed signals to save external op‑amps.
Q: Is SPI configuration mandatory?
A: This S variant relies on SPI for full parameter setup, hardware‑only pin setting is unavailable, so MCU SPI communication is required during operation.
