The TF6375–TF6380 are monolithic integrated circuits used for monitoring battery, power-supply, and regulated system voltages at extremely low power consumption. Each circuit consists of a precision bandgap reference, comparator, and internally trimmed resistors that set specified threshold voltages. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring common system voltages (e.g. 2.5V, 3V, 3.3V and 5V).
