Detailed Description
Copyright © 2015–2017, Texas Instruments Incorporated
The value of the pulldown resistor should be chosen based on the desired discharge time and acceptable
current draw in the OFF state, but no greater than 0.5 mA. Use Equation 6 to calculate the pulldown
resistor based on the desired discharge time.
where
tdischarge = discharge time of the VRTC output
RPD = pulldown resistance from the VRTC output to GND
CO = output capacitance on the VRTC line (typically 2.2 µF)
(6)
Because LDOVRTC is always on when VCC is supplied, additional current is drawn through the pulldown
resistor. The output current of LDOVRTC while the PMIC is in OFF state should not exceed 0.5 mA. Use
Equation 7 to calculate the pulldown current.
where
IPD = current through the pulldown resistor
RPD = pulldown resistance from the VRTC regulator
(7)
To use comparators in the system:
The VSYS_HI and VSYS_LO thresholds are defined in the OTP. Software cannot change these levels.
After startup, the VSYS_MON comparator is automatically disabled. Software can select new threshold
levels using the VSYS_MON register and then enable the comparators.
To have the same coding for rising and falling edge, the VSYS_MON comparator does not include
hysteresis and thus can generate multiple interrupts when the voltage level is at threshold level. New
interrupt generation has a 125-µs debounce time. This time lets software mask the interrupt and
update the threshold level or disable the comparator before receiving a new interrupt.
Figure 5-27 shows more details on VSYS_MON comparator. When the VSYS_MON comparator is
enabled, and the internal buffer is bypassed, the input impedance at VCC_SENSE pin is 500 kΩ (typical).
When the comparator is disabled, the VCC_SENSE pin is in the high-impedance state. If GPADC is
enabled to measure channel 2 or channel 3, 40 kΩ is added in parallel to the corresponding comparator.
See Table 5-9 for GPADC input range.
To enable system voltage sensing above 5.25 V, an external resistive divider can be used. Internal buffers
can be enabled by setting the OTP bit HIGH_VCC_SENSE to 1 to provide high impedance for the external
resistive dividers. The maximum input level for the internal buffer is VCCA – 1 V.
