Product Summary
The TC620CVOA is a programmable logic output temperature detector. The TC620CVOA designed for use in thermal management applications. The TC620CVOA features an on-board temperature sensor, dual thermal interrupt outputs (high limit and low limit), each of which program with a single external resistor. On the TC620CVOA is driven active (high)when measured temperature equals the user-programmed limits. The control (hysteresis)output is driven high when temperature equals the high limit setting, and returns low when temperature falls below the low limit setting. The TC620CVOA can be used to provide simple ON/OFF control to a cooling fan or heater. The TC620CVOA is usable over a maximum temperature range of – 40°C to +125°C.The applications of the TC620CVOA include (1)Power supply overtemperature detection; (2)Consumer equipment; (3)Temperature regulators; (4)CPU thermal protection.
