Key Features
- Factory-programmable voltage threshold for system-specific brownout detection without external components
- Push-button manual reset input with hardware debounce eliminates external RC debounce circuitry
- Active-low open-drain RESET output drives multiple logic loads with configurable timeout (140 ms typical)
- Compact 8-pin Thin MLF (2x2 mm) package suited for space-constrained portable and IoT designs
Applications
The MIC2788-XYMT TR is used in microcontroller-based systems that require accurate supply voltage monitoring combined with a user-accessible manual reset button, such as industrial control panels, handheld instruments, and IoT edge nodes. Its debounced push-button input prevents spurious resets caused by contact bounce, ensuring a clean reset pulse of at least 140 ms to reliably restart a processor or FPGA. The tiny 8-pin Thin MLF package and single-IC integration of supervisor and manual reset simplify PCB layout in battery-powered wearables and remote sensor modules.

Frequently Asked Questions
How does the MIC2788-XYMT TR handle push-button bounce, and what reset pulse width does it guarantee?
The IC integrates internal debounce logic on the MR (manual reset) pin, filtering contact transients shorter than approximately 1 ms so that a single button press generates exactly one clean reset assertion. The RESET output remains asserted for a minimum timeout of 140 ms after release, giving the MCU's on-chip POR circuitry ample time to complete its initialization sequence before code execution resumes.
What voltage monitoring capability does the MIC2788-XYMT TR provide, and how is the threshold set?
The device asserts RESET whenever the monitored supply voltage falls below a factory-programmed threshold, selectable across a range covering common rails such as 1.8 V, 2.5 V, 3.0 V, 3.3 V, or 5 V. Because the threshold is laser-trimmed at the factory, no external resistor divider is needed, reducing component count by 2 resistors and eliminating threshold-setting error from resistor tolerance.
For a 3.3 V microcontroller system, how does the 8-pin Thin MLF package of MIC2788-XYMT TR compare to a SOT-23 supervisor?
The Thin MLF (2x2 mm) package has a smaller footprint than a typical SOT-23-5 (2.9x1.6 mm when accounting for lead protrusion), and its bottom-side thermal pad improves heat dissipation. On a 4-layer IoT PCB this saves approximately 5 mm² per reset supervisor, which matters when routing a 3.3 V supervisor alongside an LDO and MCU in a 20x20 mm module area.
Can the MIC2788-XYMT TR be used to supervise a dual-supply system monitoring both 3.3 V and 5 V rails?
A single MIC2788-XYMT TR monitors one supply rail per device. For a dual-rail 3.3 V and 5 V system, two devices are used—one per rail—with both RESET outputs wire-OR'd together through open-drain connections. This configuration asserts a system reset if either rail drops below its respective threshold, providing complete multi-rail supervision with only 2 ICs and no additional logic gates.
