产品概述
The MAX811MEUS+T is a low power microprocessor (μP) voltage monitor with manual reset input in 4 pin SOT-143 package. This supervisory circuit is used to monitor power supplies in μP and digital systems. The MAX811 has an active-low push-pull RESET output (which has to be in the correct state for VCC down to 1V). It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V powered or 3V powered circuits. The MAX811 also provides debounced manual reset input. This device performs single function. It asserts a reset signal whenever the VCC supply voltage falls below a preset threshold, keeping it asserted for 140ms after VCC has risen above reset threshold. The reset comparator is designed to ignore fast transients on VCC. Low supply current makes the MAX811 ideal for use in computers, controllers, battery powered equipments, intelligent instruments, critical microprocessor (μP) and microcontroller (μC) power monitoring.
- Minimum supply voltage of 1.2V
- Operating temperature range from -40°C to 85°C
- Integrated voltage monitor increases system robustness with added manual reset
- Precision monitoring of 3V, 3.3V and 5V power supply voltages
- Reset threshold voltage of 4.38V at TA = +25°C and reset active timeout period of 560ms
- Power supply transient immunity
- Requires no external components and saves board space
- Low power consumption simplifies power supply requirements
- Supply current of 6μA at VCC = 5.5V and IOUT = 0
- RESET (complementary) output voltage of 0.4V (ISINK = 3.2mA, VCC = VTH(MIN))
