MXD1811 Overview
Description
The MXD1810–MXD1813/MXD1815–MXD1818 family of microprocessor (μP) reset circuits monitor power supplies in μP and digital systems. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +2.5V/+3.0V/+3.3V (MXD1815–MXD1818), and +5V (MXD1810–MXD1813) systems.
Key Features
- a debounced manual-reset feature that asserts a reset if the RESET pin is pulled low for more than 1.5μs
- When used to initiate manual reset, RESET debounces signals from devices such as mechanical switches
- For devices with this feature, the release of the external switch triggers the reset period
- The MXD1810–MXD1813/MXD1815–MXD1818 are guaranteed to output the correct logic state for VCC down to +1V
- These ICs provide a reset comparator designed to ignore fast transients on VCC
- Reset thresholds are available between +2.18V and +4.62V
- These small, low-power (4μA) devices are ideal for use in portable equipment
- All are available in space-saving 3-pin SC70 and SOT23 packages, and are specified from -40°C to +105°C
