Product Overview
The MXD1818UR22+T is a low power µP reset circuit in 3 pin SOT-23 package. This circuit monitors power supply in µP and digital systems, it provides excellent circuit reliability, low cost by eliminating external components and adjustments when used with +2.5V, +3V and +3.3V systems. Circuit asserts a reset signal whenever VCC declines below preset threshold, keeping reset asserted for at least 100ms after VCC rises above reset threshold and also keep reset asserted for at least 100ms after output is momentarily pulled to GND by an external pushbutton switch. It has an open-drain active-low RESET (complementary) output. This open-drain device has an internal pull-up resistor to VCC. It features a debounced manual-reset that asserts reset if the RESET (complementary) pin is pulled low for more than 1.5µs. It is used in critical µP and µC monitoring, printers, set-top boxes, intelligent instruments, computers and controllers.
- Supply voltage range is 1.2V to 5.5V, power supply transient immunity
- Operating temperature range from -40°C to 105°C
- Precision monitoring of +2.5V, +3V, +3.3V and +5V power supply voltages
- Factory set reset threshold voltage of 2.18V, debounced manual reset detect
- IC provides a reset comparator designed to ignore fast transients on VCC
- ±2.5% reset threshold accuracy over temperature, no external components
- Fixed reset timeout period of 100ms (min), low power consumption (4µA)
- RESET/RESET (complementary) valid to VCC = +1V
- Supply current is 16µA at VCC = +5.5V, VCC > VTH, no load
- Internal pull-up resistor, open-drain is 7.5Kohm
Applications
System Monitoring, Portable Devices, Consumer Electronics
