Frequently Asked Questions
What isolation voltage does the TMCS1108A1UQDT support?
The TMCS1108A1UQDT provides up to 100 V DC working voltage isolation between the current-carrying conductors and the signal output pins, making it suitable for motor drives and power converters where the current path operates at elevated potentials.
What is the sensitivity of the TMCS1108A1UQDT?
The TMCS1108A1UQDT (A1 variant) has a sensitivity of 400 mV per ampere, allowing the output voltage to swing proportionally to the measured current and giving good resolution when interfacing with a 3.3 V or 5 V ADC input.
Does the TMCS1108A1UQDT require an external reference voltage?
No, the TMCS1108A1UQDT includes an internal reference voltage output pin, which can be used directly as the midpoint reference for the analog output. This eliminates the need for an external precision reference in many designs, reducing component count.
What is the operating temperature range of the TMCS1108A1UQDT?
The TMCS1108A1UQDT is rated for operation from -40°C to +85°C, covering commercial and industrial temperature ranges, and is appropriate for use in outdoor power equipment, motor controllers, and factory automation environments.
What package does the TMCS1108A1UQDT come in and what are its dimensions?
The device is housed in an 8-pin SOIC surface-mount package measuring approximately 4.9 mm × 3.9 mm × 1.75 mm, making it compact enough for high-density power conversion PCBs while still providing adequate creepage for 100 V isolation applications.
