_______________Detailed Description
A microprocessor’s (P) reset input starts or restarts the
P in a known state. The reset output of the MAX6316–
MAX6322 P supervisory circuits interfaces with the
reset input of the P, preventing code-execution errors
during power-up, power-down, and brownout condi-
tions (see the Typical Operating Circuit). The MAX6316/
MAX6317/MAX6318/MAX6320/MAX6321 are also capa-
ble of asserting a reset should the P become stuck in
an infinite loop.
Reset Output
The MAX6316L/MAX6318LH/MAX6319LH feature an
active-low reset output, while the MAX6317H/
MAX6318_H/MAX6319_H/MAX6321HP/MAX6322HP
feature an active-high reset output. RESET is guaran-
teed to be a logic low and RESET is guaranteed to be a
logic high for VCC down to 1V.
The MAX6316–MAX6322 assert reset when VCC is below
the reset threshold (VRST), when MR is pulled low
(MAX6316_/MAX6317H/MAX6319_H/MAX6320P/
MAX6322HP only), or if the WDI pin is not serviced within
the watchdog timeout period (tWD). Reset remains assert-
ed for the specified reset active timeout period (tRP) after
VCC rises above the reset threshold, after MR transitions
low to high, or after the watchdog timer asserts the reset
(MAX6316_/MAX6317H/MAX6318_H/MAX6320P/
MAX6321HP). After the reset active timeout period (tRP)
expires, the reset output deasserts, and the watchdog
timer restarts from zero (Figure 2).
