DS1621V Description

Short technical summary and product information.

The DS1621V is a digital thermometer and thermostat IC from Dallas Semiconductor, designed to provide temperature monitoring and control for various systems. It accurately measures temperatures within a range of -55°C to +125°C, with a resolution of 0.5°C.

 

This device communicates temperature readings and settings via a simple 2-wire serial interface, making integration straightforward. It operates over a wide power supply range of 2.7V to 5.5V. The DS1621V also includes a thermostat function with user-definable settings stored in non-volatile memory, allowing the T_OUT pin to signal when temperatures exceed a set threshold.

 

Designed for space-saving applications, the DS1621V requires no external components for temperature measurements. It is available in an 8-pin SO package, suitable for surface mounting. This component is ideal for applications such as thermostatic controls, industrial systems, and consumer products where precise temperature monitoring is essential.
