概述
Description
TMCS1101A3UQDRQ1 is a Texas Instruments isolated current-sense monitor IC. It measures the voltage across a sensing resistor in the high-current path and provides a signal on the isolated output that a microcontroller or ADC can read. The galvanic isolation separates the high-power side from the logic side, enabling safe monitoring of high-side or low-side currents in power supplies, motor drivers, and battery-management systems. The A3UQDRQ1 suffix encodes packaging, temperature grade, and RoHS/compliance details. For exact electrical specs, sense-resistor recommendations, pinout, and timing, consult the TMCS1101A datasheet and product page.
Pinout
Pin count: 8 pins.
Function: A single‑channel galvanically isolated current‑sense monitor. It has two isolated power rails: primary side (VCC1, GND1) and secondary side (VCC2, GND2). The primary side includes the input sense pins (IN+ / IN−) for the shunt voltage; the secondary side provides the isolated output (VO) proportional to the sensed current. (Exact pin names depend on the package variant; refer to the datasheet for the pinout.)
