Notes

63.

For 1.8 V ISNVS limited to 100 A for VCOIN < 2.1 V

64.

The start-up of VSNVS is not monotonic. It first rises to 1.0 V and then settles to its programmed value within the specified tR1 time.

65.

From coin cell insertion to VSNVS =1.0 V, the delay time is typically 400 ms.

66.

During crossover from VIN to LICELL, the VSNVS output voltage may drop to 2.7 V before going to the LICELL voltage. Though this is

outside the specified DC voltage level for the VDD_SNVS_IN pin of the i.MX 6, this momentary drop does not cause any malfunction.

The i.MX 6’s RTC continues to operate through the transition and as a worst case, it may switch to the internal RC oscillator for a few

clock cycles before switching back to the external crystal oscillator.

Table 95. VSNVS Electrical Characteristics (continued)

All parameters are specified at TA = -40 to 85 °C, VIN = 3.6 V, VSNVS = 3.0 V, ISNVS = 5.0 A, typical external component values,

unless otherwise noted. Typical values are characterized at VIN = 3.6 V, VSNVS = 3.0 V, ISNVS = 5.0 A, and 25 °C, unless

otherwise noted.
