Data Sheet

REGISTER 7: LCH_CFG (SHORT-CIRCUIT LATCH-OFF

AND OVERVOLTAGE LATCH-OFF CONFIGURATION),

ADDRESS 0x07

Register 7 is used to enable and disable the latch-off function for

short-circuit protection (SCP) and overvoltage protection (OVP).

When the SCP or OVP latch-off function is enabled, the

CHx_LCH bit in Register 12 is set after an error condition

occurs (see the Latch-Off Protection section). The default value

for the SCP latch-off and OVP latch-off functions can be

programmed by factory fuse (SCP or OVP latch-off function

enabled or disabled for all four buck regulators).
