EEPROM-Programmable, Hex
Power-Supply Supervisory Circuits
UV / OV
Program UV / OV to depend on MR , RESET , or any pro-
grammable secondary voltage detector input (see Table
7). As an example, UV / OV may depend on the IN1 sec-
ondary overvoltage threshold, MR , and RESET . Write 1’s
to R13h[2:0] and R0Eh[1] to configure as indicated. IN1
must be below the overvoltage threshold, MR must be
high, and RESET must be deasserted to be a logic “1,”
Table 7. Programmable UV / OV Options
then UV/OV deasserts. The logic state of UV / OV , in this
example, is equivalent to the logical statement:
IN1 · MR · RESET
UV / OV remains low for its programmed time delay (t UP )
after all assertion-causing conditions are removed.
Program time delays for UV / OV from 25μs to 1600ms
(see Table 7). Configure UV / OV for open drain or weak
pullup through bit R14h[0].
