STMicroelectronics 

STM1810 STM1811 STM1812 STM1813

STM1815 STM1816 STM1817 STM1818

Low power reset circuit

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)

SOT23-3 (WX)

● 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.
