    Products Detail

    ST7538QTR Description


    System monitor IC ST7538QTR from STMicroelectronics is intended for high-accuracy power supply voltage monitoring in industrial and automotive systems. It is a small, low-voltage device with an operational temperature range of -40°C to +125°C that can resist challenging operating conditions. When the voltage goes below a preset threshold level, the ST7538QTR checks the supply voltage and sends out an output reset signal to make sure that linked microcontrollers and other digital circuits are safely and securely switched off. The device includes a 2.63V internal reference voltage, as well as choices for different combinations of thresholds and hysteresis to fulfill varied application requirements. It also allows programmable time delay using an external capacitor. The ST7538QTR is appropriate for space-constrained automotive applications including Advanced Driver Assistance Systems (ADAS), Engine Management Systems, Vehicle-to-Vehicle (V2V) communication, and other safety-critical systems since it is offered in a tiny and space-saving QFN16 package.



    ST7538QTR Features


    • A small and compact QFN16 package.

    • Low quiescent current of just 10μA (TYP).

    • Operating voltage range from 4.5V to 40V.

    • Adjustable reset time delay using an external capacitor.

    • Wide operational temperature range (-40°C to +125°C).

    • Power-on reset output signal with push-pull or open-drain option.

    • Integrated 2.63 V reference voltage with a low temperature coefficient.

    • High accuracy voltage threshold detection with programmable hysteresis.



    ST7538QTR Applications


    • Medical equipment such as patient monitors, diagnostic devices, and imaging systems.

    • Audio/Video systems for powering TVs, audio amplifiers, and other multimedia equipment.

    • Power-sensitive battery-operated devices like portable tools, IoT devices, and home automation.

    • Advanced Driver Assistance System (ADAS), Vehicle-to-Vehicle (V2V) communication systems, etc.

    • Automotive electronics including Engine Management Systems (EMS), Electronic Stability Control (ESC),

    • Industrial control equipment such as motor drives, power supplies, Programmable Logic Controllers (PLCs), machine vision, and robotics.
