The MC623 3.0V dual trip point temperature sensor is a 3.0V solid-state, programmable temperature sensor designed for use in thermal management applications. It features dual thermal interrupt outputs (LOW LIMIT and HIGH LIMIT) each of which program with a single external resistor. When measured temperature exceeds the user-programmed limits, the HIGH LIMIT and LOW LIMIT outputs are driven active (high). When temperature exceeds the HIGH LIMIT setpoint, the CONTROL output is driven active (high), and turned off when temperature falls below the LOW LIMIT setpoint. The CONTROL output can be used to provide simple ON/OFF control to a cooling fan if so desired. Low voltage operation, easy setpoint programming, small size and low cost make the MC623 an ideal choice for many thermal management applications.
The MC623 is a 3.0V solid-state, programmable temperature sensor designed for thermal management applications. It features dual thermal interrupt outputs (LOW LIMIT and HIGH LIMIT) that can be programmed with a single external resistor. The device includes a CONTROL output for simple ON/OFF control, such as driving a cooling fan, and operates from a supply voltage as low as 2.7V.
| Supply Voltage Range | 2.7 V to 4.5 V |
|---|---|
| Operating Temperature Range | -40°C to 85°C |
| Maximum Chip Temperature | 150 °C |
| Package Type | 8-Pin SOIC |
