Thermal Monitor

The UC1730 family of integrated circuit devices are designed to be used in a number of thermal monitoring applications. Each IC combines a tempera- ture transducer, precision reference, and temperature Comparator allowing the device to respond with a Logic output if temperatures exceed a user pro- grammed level. The reference on these devices is capable of supplying in excess of 250mA of output current by setting a level of power dissipation the rise in die temperature will vary with airflow past the package, allowing the IC to respond to airflow conditions These devices come in an 8-Pin DIP, plastic or ceramic, a 5-Pin TO-220 or a PLCC-20 version. In the 8-Pin version, a PTAT (proportional to absolute temperature) output reports die temperature directly. This output is config- ured such that its output level CAN be easily scaled up with two external gain resistors. A second PTAT source is internally referenced to the temperature Comparator The other input to this Comparator CAN then be externally pro- grammed to set a temperature threshold. When this temperature threshold is exceeded an alarm delay output is activated. Following the activation of the delay output, a separate Open Collector output is turned on. The delay pin CAN be programmed with an external RC to provide a time separation between activation of the delay pin and the alarm pin, permitting shutdown diagnostics in applications where the Open Collector outputs of multiple parts are wire ORed together. The 5-Pin version in the TO-220 package is well suited for monitoring heatsink temperatures. Enhanced airflow sensitivities CAN be obtained with this package by mounting the device to a small heatsink in the airstream. This version of the device does not include the PTAT output or the open col - lector alarm output. By Texas Instruments
