Figure 1: functionality of the SP6339 and SP6341.
V1 > Vth1, V2 > Vth2 , and V3 > Vth3 (all supplies over their corresponding thresh-
olds)----> RSTB is de-asserted after reset timeout period (Trp) & WDOB de-asserts
immediately without waiting for reset timeout period.
MRIB goes to “LOW” to force “Reset” ----> RSTB is asserted immediately & WDOB is
not affected by MRIB and is not asserted.
WDI keeps making transitions within watchdog timeout period (t<Twd) ----> neither
RSTB nor WDOB changes state.
One of the supplies drops below its corresponding threshold (in this case V3) ---->
RSTB is asserted immediately & WDOB is asserted immediately too. Whenever V1, V2,
V3 are below their specified thresholds WDOB is asserted.
