Notes
9. Operation with the Charge Pump is recommended when minimum system voltage could be less than 14 V. V PWR must exceed this
threshold in order for the Charge Pump and V DD regulator to startup and drive V PWR to > 8.0 V. Once V PWR exceeds 8.0 V, the circuits
will continue to operate even if system voltage drops below 6.0 V.
10. This parameter is guaranteed by design. It is not production tested.
11. Minimum external capacitor for stable V DD operation is 0.47 μF.
12.
13.
14.
Recommended external capacitor for the V LS regulator is 2.2 μF low ESR at each pin VLS and VLS_CAP.
When V LS is less than this value, the outputs are disabled and HOLDOFF circuits are active. Recovery requires initialization when V LS
rises above this threshold again. A filter delay of approximately 700 ns on the comparator output eliminates responses to spurious
transients on V LS .
See Figure 11 for typical capability to maintain gate voltage with a 5.0 μA load.
