  • Description

    The STM1E-SFP03 is an IC chip in the electronic components category. The STM181x device is a low-power reset device used to monitor power supplies for microcontrollers, which performs a single function. It asserts a reset signal whenever VCC supply voltage drops below a preset value and keeps it asserted until VCC has risen above the preset threshold for a minimum period of time. It provides excellent circuit reliability without additional external components when used with +3.0 V / +3.3 V (STM1815–STM1818), and +5 V (STM1810–STM1813) power supply systems.

    Specifications and features
