(typical) 5-Lead SOT-23 Package Microchip Technology’s MCP9501/2/3/4 family devices
are temperature switches with В±1В°C (typical) accurate
factory set output thresholds. These devices are ideal for
high-power supply systems where an overtemperature
protection circuit is needed. These devices do not
require external components, consume 25 ВµA (typical),
and the factory set thresholds provide simplicity. …
