Configuration Registers
The device is configured for specific application requirements using the Configuration Registers. The configuration register
consists of SRAM memory. This memory is powered by the RGO output. In a sleep condition, an internal switch powers the
contents of these registers from the VCELL1 input.

When set to ‘0’, a discharge overcurrent condition automatically turns off the FETs.
When set to ‘1’, a discharge overcurrent condition will not automatically turn off the FETs.
In either case, this condition sets the DOC bit, which also turns on the TEMP3V output.

V OCD = 0.10V
V OCD = 0.12V
V OCD = 0.14V
V OCD = 0.16V
When set to ‘0’, a discharge short circuit condition turns off the FETs.
When set to ‘1’, a discharge short circuit condition will not automatically turn off the FETs.
In either case, the condition sets the SCD bit, which also turns on the TEMP3V output.

t OCD = 320ms (5ms if DTDIV = 1)
t OCD = 640ms (8ms if DTDIV = 1)
t OCD = 1280ms (16ms if DTDIV = 1)
