DESCRIPTION
Negative reference for all signals.
Active low reset output. When the sense threshold has been exceeded, the RESET signal will
remain active for an additional 140ms (min.) after which it becomes inactive. During a "brownout"
condition, RESET will immediately become active. Internal circuitry ensures RESET will remain
active even when the supply voltage is as low as 0V.
Supply input signal which is monitored by the sense comparator. This input is compared to the
2.93V (CM3403-29ST/SO) or 4.63 (CM3403-46ST/SO) reference to determine the state of the out-
put.
