Features & Applications
The STM1818TWX7F is a low power reset devices used to monitor power supplies for microcontrollers. They perform a single function: asserting a reset signal whenever VCC supply voltage drops below a preset value and keeping it asserted until VCC has risen above the preset threshold for a minimum period of time (trec).
They provide 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.
Features:
- Precision monitoring of 3 V, 3.3 V, and 5 V supply voltages
- Four output configurations:
- Push-pull, active-high (STM1812,1817)
- Push-pull, active-low (STM1810,1815)
- Open-drain, active-low (STM1811,1816)
- Open-drain, active-low with push-button detect (STM1813,1818)
- Reset pulse width - 100 ms (min.)
- Low supply current - 4 μA (typ.)
- Guaranteed assertion down to VCC = 1.0 V (0 °C to 105 °C)
- Factory-trimmed reset thresholds of 2.55 V, 2.88 V, 3.06 V, 4.37 V, and 4.62 V (typ.)
- Power supply transient immunity
- Push-button/manual reset detect (STM1813/1818)
- Operating temperature: –40 °C to 105 °C
- ± 2.5% reset threshold accuracy: (–40 °C to 105 °C)
- Available in the SOT23-3 package
- Fully compatible with DS181x and MXD181x products
