TITMCS1108A4BQDRQ1
Overview
The TMCS1108A4BQDRQ1 is an AEC-Q100 qualified, galvanically isolated Hall-effect current sensor designed for high-precision DC or AC current measurement. It features a ratiometric voltage output with a high sensitivity of 400mV/A and a 100V isolation rating, making it suitable for low-to-medium voltage systems requiring functional safety. The device integrates a zero-drift internal reference to maintain accuracy across its -40C to 125C operating temperature range.
Why Choose This Part
The sensor offers excellent linearity of +/-0.5% and a zero-drift architecture that minimizes offset errors over temperature. Its 80kHz bandwidth and 6.5us response time provide sufficient speed for most motor control and power monitoring loops. Being AEC-Q100 qualified and functional safety-capable, it simplifies the certification process for automotive and industrial safety systems.
Applications
Key Specifications
Getting Started
To evaluate this sensor, use the TMCS1108EVM evaluation module which provides a hardware platform for testing accuracy and transient response. Ensure the PCB layout follows Texas Instruments' recommendations for thermal management of the high-current trace to avoid localized heating. The ratiometric output can be interfaced directly to a 3V or 5V microcontroller ADC, as the device operates between 3V and 5.5V VDD.
