概述

Description

DRV8243SQRXYRQ1 is a TI motor-driver IC from the DRV824x family. It provides two high-side/low-side MOSFET bridges (dual full-bridge) to drive DC motors or stepper motors from a single supply. Key features include programmable current regulation (via a reference resistor), fault protection (overcurrent, undervoltage, overtemperature, short to GND or VCC) with a FAULT flag, and flexible control through logic inputs (per-bridge IN pins) or PWM for speed control, along with enable/sleep control. It supports PWM current regulation and multiple decay modes for smoother operation. The SQRXYRQ1 suffix specifies the package/ordering variant used by TI. Typical applications are compact motors in robotics, printers, and similar equipment. For exact electrical specs, pinout, and package details, consult the TI datasheet and product page.

Features

Key features of DRV8243SQRXYRQ1 (dual high‑current motor driver):
- Two full-bridge DMOS outputs for two motors or one bipolar stepper
- Wide operating voltage range suitable for DC and stepper motors
- PWM current regulation with adjustable current limit (via external reference)
- Multiple current decay modes for smooth torque control
- Independent channels with protection and fault reporting
- Protections: undervoltage lockout, overcurrent protection, overtemperature shutdown
- Fault/diagnostic reporting (DIAG/FLT) for monitoring
- Enable, Sleep/Standby control for power saving
- Shoot-through protection and fast/reliable fault handling
- Compact package option (SQRXYRQ1 variant) suitable for dense layouts
Note: exact voltage/current ratings and pins vary by package. Please consult the TI datasheet for precise electrical specifications and pinout.

Package

HTSSOP-28 (28-pin thin shrink small-outline package).

Pinout

- Pin count: 28 pins.
- Function: TI DRV8243SQRXYRQ1 is a two-channel (dual) full-bridge motor driver (two H-bridges) for DC motors or a stepper motor. It provides high-side/low-side outputs with programmable current regulation (PWM), plus protections (OC/UVLO/OT), and fault/diagnostic reporting. Control inputs typically include IN1/IN2 (channel A) and IN3/IN4 (channel B) with enable/sleep as applicable.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: A global American semiconductor company that designs and manufactures analog and embedded processing ICs (and other semiconductor products). TI is headquartered in Dallas, Texas and is one of the world’s leading suppliers of analog and mixed-signal chips.

Application

Application areas:
- Robotics and automation (driving small DC motors and actuators)
- Consumer electronics and appliances (printers, fans, actuators)
- Automotive and industrial actuators (door locks, HVAC actuators)
- General low-voltage DC motor drive applications requiring current regulation and protection
(Uses include compact, protected motor drive in dual/dual‑motor setups; suitable for systems needing reliable overcurrent and fault protection.)

Equivalent

Not a direct one-to-one cross-reference. TI’s closest substitutes are other dual-H-bridge motor drivers with similar voltage/current ranges, such as DRV8412 and DRV8834. For non-TI options, consider Allegro A4988/A4983 and Trinamic TMC2100/TMC2130, depending on features. Use TI’s Cross Reference tool and compare voltage/current, packaging, and control interface to pick a replacement.
