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)

●

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.
