6.4.2. Unconditional Hardware Reset
To unconditionally restart the LM960 module, the SYSTEM_RESET_N pin must be
asserted low more than 1 seconds and then released.
Unconditional Hardware Reset by SYSTEM_RESET_N Pad
Information – The Unconditional Hardware Reset must be used only
as an emergency exit procedure, and not as a normal power-off
operation.
Information – Do not use any pull-up resistor on the RESET_N line or
any totem pole digital output. Using a pull-up resistor may cause latch-
up problems on the LM960 power regulator and improper functioning
of the module. The RESET_N line must be connected only in an open-
collector configuration.
