PRODUCTION DATA
The undervoltage lockout circuit prevents the device from malfunction at low input voltages and from excessive discharge of the battery, and disables the converters. The undervoltage lockout threshold is typically 1.5 V; maximum of 2.35 V. In case the interface overwrites the default register values, the new values in the registers REG_DEF_1_High, REG_DEF_1_Low and REG_DEF_2 remain valid as long the supply voltage does not fall below the undervoltage lockout threshold, independent of disabling of the converters.
