description
The TPS3307-18 is a micropower supply voltage supervisor designed for circuit initialization primarily in
automotive DSP and processor-based systems, which require more than one supply voltage.
The TPS3307-18 is designed for monitoring three independent supply voltages: 3.3 V/1.8 V/adj,. The adjustable
SENSE input allows the monitoring of any supply voltage >1.25 V.
The various supply voltage supervisors are designed to monitor the nominal supply voltage as shown in the
following supply voltage monitoring table.
