DS1834A Description

Short technical summary and product information.

The DS1834A is a dual voltage supervisor IC designed by Analog Devices / Maxim Integrated to monitor critical system power conditions. It specifically monitors both 3.3V and 5V power supplies, asserting a reset signal when either supply falls out of tolerance. This device is ideal for systems designed to operate with dual power supplies, ensuring system stability during power transients.

 

Key features include a precision temperature-compensated voltage reference and sensor, an internally debounced pushbutton reset input for manual system override, and a reset timeout of 200ms minimum. The reset signal is active low and maintains reset for approximately 350ms after the power supply returns to an in-tolerance condition. The internal power is drawn from the higher of the two input voltages.

 

The DS1834A is available in an 8-pin PDIP package and is suitable for through-hole mounting. It operates within a temperature range of -40°C to +85°C (TA). This component reduces the need for discrete components in power monitoring applications.
