Présentation

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.)

Manufacturer

Manufacturer: Texas Instruments Incorporated (TI).
What kind of company: A multinational American semiconductor company that designs and manufactures analog and embedded processing integrated circuits for automotive, industrial, consumer electronics, and other applications.

Application

TMCS1101A3UQDRQ1 is a galvanically isolated current-sense device. Common applications include:
- Motor control and drives (BLDC/PMSM, stepper)
- Isolated feedback for DC-DC converters and power supplies
- Automotive powertrains, battery-management systems, charging
- Renewable energy inverters (solar, energy storage)
- Industrial automation and smart sensors requiring high-voltage isolation
These areas leverage its isolated current sensing and protection capabilities.

Package

8-pin QFN (VQFN) package, 3.0×3.0 mm, with an exposed thermal pad.
