Description

The SiP823/SiP824/SiP825 series are Processor  supervisory circuits in a 5-pin SOT23 package, that combine the functions of power supply and Processor monitoring. If the power supply voltage drops, or has been, below a safe level or the Processor shows signs of problematic inactivity, the circuit will generate a reset signal at it's output.

The SiP823 and SiP825 have an input to accommodate manual reset.Seven pre-programmed reset threshold voltage levels are available as standard options.Specially configured options are available upon request, allowing for further customization of reset voltage, reset time-out, and watchdog time-out periods.

The SiP823 has a reset output that is "active low" and the  SiP824 and SiP825 have complementary outputs for both "active high" and "active low" resets. Both output drives are push/pull configurations.Space saving SOT23-5 packages and low quiescent current make this family of products ideally suited for portable battery operated equipment.

These circuits SiP825 fully ignore fast negative VCC transients and have valid reset output signals with power supply levels down to 1 V.
