DS1832S Description

Short technical summary and product information.

The DS1832S by Dallas Semiconductor is a 3.3-volt MicroMonitor designed to monitor critical conditions for microprocessors. It provides power supply monitoring, ensuring the system is warned of impending power failures and that resets are held active during power transients.

 

The device also incorporates pushbutton reset control with debouncing and guarantees an active reset pulse width. Additionally, it features a watchdog timer function that can be set to various timeout periods, forcing a reset if the strobe input is not serviced.

 

Key features include accurate 10% or 20% power monitoring, eliminating the need for discrete components. The DS1832S is pin-compatible with the DS1232 and is available in an 8-pin SOIC package. It operates within an industrial temperature range of -40°C to +85°C.

 

This MicroMonitor is suitable for applications requiring robust power supervision and system reset management, ensuring reliable microprocessor operation.
