Notes

8.

When minimum system voltage could be less than 14V operation with the Charge Pump is recommended. VBAT must exceed this

threshold in order for the Charge Pump and VDD regulator to startup and drive VPWR to > 8.0V. Once VPWR exceeds 8.0V, the circuits

will continue to operate even if VBAT drops below 6.0V.

9.

This parameter is guaranteed by design. It is not production tested.

10.

Minimum external capacitor for stable VDD operation is 0.47µF.

11.

Recommended external capacitor for the VLS regulator is 2.2µF low ESR at each pin VLS and VLS_CAP.

12.

When VLS is less than this value, the outputs are disabled and HOLDOFF circuits are active.
