Working Principles

The MCP6549T-E/STVAO operates as a voltage comparator, comparing the voltage at the Vin+ pin with the reference voltage (Vref) at the Vin- pin. When the voltage at Vin+ is higher than Vref, the output switches to a logic high level. Conversely, when the voltage at Vin+ is lower than Vref, the output switches to a logic low level. The open drain and push-pull output options allow the user to choose the appropriate output configuration based on the application requirements.
