Description

STM181x devices are 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 PushButton 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.
