DS1830A Datasheet Reset Sequence Pushbutton

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: www.maxim-ic.com.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

1 PBRST - Pushbutton Reset Input 2 TD - Time Delay Select Input 3 TOL 4 GND - VCC Tolerance Select Input - Ground 8 VCC 7 RST1 - Power Supply - Reset 1 Output 6 RST2 - Reset 2 Output 5 RST3 - Reset 3 Output DESCRIPTION The DS1830 Reset Sequencer monitors the power supply for an in-tolerance condition and the pushbutton reset input for a manual reset.

First a precision temperature-compensated reference and comparator circuit monitors the status of the power supply and when an out-of-tolerance condition is detected, an internal power fail signal is generated that forces the reset lines to go to an active state.

If the power supply returns to an in-tolerance condition, RST1 will release followed by RST2 and finally RST3 .

Key Features

  • 5V (DS1830) or 3.3V (DS1830A) power-on reset.
  • Excellent for systems that need power-on resets in a consistent sequence.
  • Asserts resets during power transients.
  • Pushbutton reset input for system override.
  • Selectable reset timing.
  • Reduces need for discrete components.
  • Precision temperature-compensated voltage reference.
  • 8-pin DIP, 8-pin SO, or space saving 8-pin µSOP.
  • Operating temperature of -40°C to +85°C.
  • Open-drain, active-low inputs DS1830/A.
