3515A Description
The UTC 3515A is specially designed for switching power supply system. it provides protection circuits, power good output (PGO) indicator, fault protection output (FPOB) and a PSONB control. The protection circuits include over voltage protection (OVP), under voltage protection (UVP) and over current protection (OCP) monitoring for system voltages and currents.
3515A Key Features
- OVP/UVP monitors 3.3V, 5V, 12V input voltage level
- OCP monitors IS33, IS5, IS12 input current sense
- Fault protection output (FPOB) with Open Drain Output stage
- Power good output (PGO) with Open Drain Output stage
- 38ms de-bounce time for PSONB input signal
- 300ms time delay from PGI to PGO
- 2.4ms time delay for PSONB to turn off FPOB
