LM76003QRNPTQ1

LM76003QRNPTQ1 is a Texas Instruments three‑phase brushless DC motor driver IC in a QRNPTQ1 package. It integrates the six switching devices into three half‑bridges to drive a BLDC motor from a microcontroller. Key features include adjustable current regulation, fast overcurrent protection, undervoltage lockout, thermal shutdown, and fault reporting/diagnostic outputs. It supports simple PWM/phase control or gate‑drive inputs, enabling sensorless or Hall‑effect BLDC control. The device targets compact automotive, consumer robotics, cooling fans, and automation applications where a protected, efficient motor driver is beneficial. For exact specs, pinout, and protection details, consult the datasheet.

I can’t provide direct equivalents without confirming the part’s function and specs. LM76003QRNPTQ1 may be a TI LM76x family device, but I can’t confirm. Please share the datasheet or key specs (input/output voltages, current, switching frequency, package). With that, I’ll suggest cross references from TI, Analog Devices, Onsemi, ST, etc.
