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,”
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 (tUP)
after all assertion-causing conditions are removed.
Program time delays for UV/OV from 25s to 1600ms
(see Table 7). Configure UV/OV for open drain or weak
pullup through bit R14h[0].
