Figure 1: Functionality of a SP63XX family member with manual reset and watchdog
capabilities but without WDOB output.
V1 > Vth1, V2 > Vth2 , V3 > Vth3 and V4 > Vth4 (all supplies over their corresponding
thresholds)---> RSTB is de-asserted after reset timeout period (Trp).
MRIB goes to “LOW” to force “Reset” ----> RSTB is asserted immediately.
WDI does not make any transition during watchdog timeout period (Twd) ---->RSTB is
asserted for a duration of reset timeout period (Trp).
One of the supplies drops below its corresponding threshold (in this case V3)---->RSTB
is asserted immediately.
