If the power supply voltage drops, or has been, below a safe level or the mProcessor 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 fam...
