Description
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)
■ Operating temperature: –40 °C to 105 °C
SOT23-3 (WX)
■ ± 2.5% reset threshold accuracy: (–40 °C to 105 °C)
■ Available in the SOT23-3 package ■ Fully compatible with DS181x and MXD181x
products.
