The power-up time of the IC depends in part on the time required for this regulator to charge up the external filter capacitors on VLS and
VLS_CAP. This delay includes the expected time for V DD to rise.
The charge pump operating at 12 V V SYS , 1.0 ? F pump capacitor, MUR120 diodes and 47 μF filter capacitor.
This parameter is guaranteed by characterization, not production tested.
These delays include all logic delays except deadtime. All internal logic is synchronous with the internal clock. The total delay includes
one clock period for state machine decision block, an additional clock period for FULLON mux logic, input synchronization time and
output driver propagation delay. Subtract one clock period for operation in FULLON mode which bypasses the state machine decision
block. Synchronization time accounts for up to one clock period of variation. See Figure 6 .
The maximum separation or overlap of the High and Low Side gate drives, due to propagation delays when commanding one ON and
the other OFF simultaneously, is guaranteed by design.
The output of the overtemperature comparator goes through a digital filter before generating a warning or interrupt.
This specification is based on capacitance of 0.47 μF on VDD, 2.2 μF on VLS and 2.2 μF on VLS_CAP.
