Specifications

Figure 5-3. Recommended Power-Down Sequencing

(1) Time stamps:

–

T0 = 0 ms, T1 > 100 μs, T2 = 0.5 ms, T3 = 1.0 ms, T4 = 1.5 ms; V1 = 2.7 V. All “Tn” markers are intended to show elapsed times

from T0. Delta time: Δ TD1 > 100 μs.

(2) Terminology:

–

VOPR MIN = Minimum Operational Voltage level that ensures device functionality and specified performance per Section 5.4,

Recommended Operating Conditions.

–

VOFF = OFF Voltage level is defined to be less than 0.6 V where any current draw has no impact to POH.

–

Ramp Down = transition time from VOPR MIN to VOFF and is slew rate independent.

(3) General timing diagram items:
