What are the key features of STM1810MWX7F?
- Fixed threshold voltage monitoring for 3 V, 3.3 V, and 5 V supply rails with no external components required
- Active-low push-pull reset output drives logic directly without external pull-up resistors, reducing BOM count
- Ultra-compact 3-pin SOT-23 package occupies minimal PCB area, ideal for space-constrained portable and IoT designs
What is STM1810MWX7F used for?
The STM1810MWX7F is used to assert a clean reset signal to microcontrollers and FPGAs during power-up, power-down, and brownout conditions on 3 V, 3.3 V, or 5 V supply rails. Its push-pull active-low output eliminates the need for external pull-up resistors, simplifying board design in consumer electronics, industrial controllers, and wearable devices. The tiny SOT-23 footprint makes it a drop-in supervisory solution wherever PCB space and component count must be minimized.

Frequently Asked Questions
Which supply voltages does the STM1810MWX7F supervise and what type of reset output does it provide?
The STM1810MWX7F monitors 3 V, 3.3 V, and 5 V supply rails and provides an active-low push-pull reset output, so no external pull-up resistor is needed and the reset line can drive CMOS logic inputs directly.
What package does the STM1810MWX7F use and how does its size benefit compact board layouts?
The STM1810MWX7F uses a 3-pin SOT-23 (TO-236-equivalent) package, which has a footprint of roughly 1.3 mm × 2.9 mm, making it one of the smallest available voltage supervisor packages and ideal for wearable or handheld designs where board area is limited.
Is the STM1810MWX7F adjustable or fixed threshold, and when is that suitable for a design?
The STM1810MWX7F has a fixed threshold with no adjustable pin, which simplifies design when only standard 3 V, 3.3 V, or 5 V rails need supervision and eliminates resistor divider tolerance errors that affect adjustable-threshold supervisors.
How does STM1810MWX7F compare to similar reset ICs like the MCP111 for a 3.3 V microcontroller application?
Both provide fixed-threshold voltage supervision with an active-low output in SOT-23 packages; the STM1810MWX7F supports 3 fixed voltages (3 V, 3.3 V, 5 V) in one part number variant, while MCP111 offers similar fixed thresholds — the STM1810MWX7F's push-pull output avoids the need for an external 10 kΩ pull-up resistor required with open-drain alternatives.
