Frequently Asked Questions
What is the TMCS1100A2QDR and what current range does it support?
The TMCS1100A2QDR is a Hall-effect isolated current sensor from Texas Instruments. The 'A2' gain variant supports a ±50A measurement range with a sensitivity of 200mV/A. It provides 3kVRMS galvanic isolation between the current-carrying conductor and the signal output, making it safe for both high-side and low-side current sensing in industrial and automotive applications.
What is the supply voltage and output interface of the TMCS1100A2QDR?
The TMCS1100A2QDR operates from a 3V to 5.5V supply, making it compatible with both 3.3V and 5V logic systems. The output is a ratiometric analog voltage centered at VCC/2 with a 200mV/A sensitivity, so no digital interface is needed — connect directly to an ADC input. Bandwidth is typically 450kHz.
What package does the TMCS1100A2QDR use and what are its dimensions?
The TMCS1100A2QDR comes in a compact SOT-23-6 surface-mount package with 6 pins. This small package is well-suited for board-space-constrained designs. The device integrates the current-carrying conductor internally with only 4.5mΩ resistance, eliminating the need for an external shunt resistor.
What are the typical applications for the TMCS1100A2QDR?
The TMCS1100A2QDR is commonly used in industrial motor drives for phase current sensing, battery management systems (BMS) in electric vehicles and energy storage, solar inverter DC-bus monitoring, server power supply overcurrent protection, and smart energy meters. Its wide temperature range (-40°C to 125°C) and isolated architecture make it suitable for harsh environments.
Are there compatible alternative current sensor ICs to the TMCS1100A2QDR?
Compatible alternatives include the TMCS1100A1QDR (±25A, 400mV/A, same SOT-23-6 package), TMCS1100A3QDR (±100A, 100mV/A), and the Allegro ACS712-05B (±5A) or ACS723 series for similar Hall-effect isolated sensing. For higher accuracy, the INA240 from Texas Instruments is a non-isolated precision current sense amplifier alternative.
