Maxim MAX6315US31D3-T

Простой сброс/сброс при включении питания3.08V1

Overview

The MAX6315US31D3 low-power CMOS microprocessor (μP) supervisory circuit is designed to monitor power supplies in μP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments. The MAX6315US31D3 also provides a debounced manual reset input. This device performs a single function: it asserts a reset signal whenever the VCC supply voltage falls below a preset threshold or whenever manual reset is asserted. Reset remains asserted for an internally programmed interval (reset timeout period) after VCC has risen above the reset threshold or manual reset is deasserted. The MAX6315's open-drain active-low RESET output can be pulled up to a voltage higher than VCC. The MAX6315US31D3 comes with factory-trimmed reset threshold voltages in 100mV increments from 2.5V to 5V. Preset timeout periods of 1ms, 20ms, 140ms, and 1120ms (minimum) are also available. The device comes in a SOT143 package. For microcontrollers (μCs) and μPs with bidirectional reset pins, see the MAX6314 data sheet.
