Product features

• Over-voltage protection
• Under-voltage protection
• Power-Good indication

• Internal control debounce: 38 ms
• Input noise deglitching
• Wide supply voltage range: 4 V to 15 V

The TPS5510 and ’5511 are 3-channel power supply supervisors designed to minimize external components required for personal computer switching power supply systems. Combining basic supply voltage supervision and protection circuits in a single chip, these devices reduce PCB space as well as increase system reliability. Features of the TPS5510/11 include:

• Over-voltage protection and lock-out for 12 V, 5 V and 3.3 V
• Under-voltage protection and lock-out for 5 V and 3.3 V
• Short-circuit turn-on protection
• Power-good indication
• Remote ON/OFF control with a 38-ms de-bounce
• 73-µs width noise de-glitches for all input pins
• Wide supply voltage range of 4 V to 15 V

The short-circuit turn-on protection acts to shut the system down within 75-ms of operation if it detects a short-circuit at the output, thereby preventing damage to the system. The noise de-glitches at the input pins help to filter and eliminate the effects of noise at the input end.

Both devices are characterized for operation from –40° C to 125° C and they are available in 8-pin SOIC and PDIP packages.
