4.3.1.4 Supply Voltage Supervisor and Power Good (PGOOD)

Power-good (PGOOD) is an open-drain output of the built-in voltage supervisor that monitors DCDC1, DCDC2, DCDC3, DCDC4, and LDO1. The output is Hi-Z when all enabled rails are in regulation and driven low when one or more rails encounter a fault which brings the output voltage outside the specified tolerance range. In a typical application PGOOD drives the reset signal of the SOC.

The supervisor has two modes of operation, controlled by the STRICT bit. With the STRICT bit set to 0, all enabled rails of the five regulators are monitored for undervoltage only with relaxed thresholds and deglitch times. With the STRCT bit set to 1, all enabled rails of the five regulators are monitored for undervoltage and overvoltage with tight limits and short deglitch times. Table 4-1 summarizes these details.

Table 4-1 Supervisor Characteristics Controlled by the STRICT Bit

PARAMETER STRICT = 0b (TYP) STRICT = 1b (TYP)
Undervoltage monitoring Threshold (output falling) 90% 96.5% (DCDC1, DCDC2)
95.5% (DCDC3, DCDC4, LDO1)
Deglitch (output falling) 1 ms 50 µs
Deglitch (output rising) 10 µs 10 µs
Overvoltage monitoring Threshold (output falling) N/A 103.5% (DCDC1, DCDC2)
104.5% (DCDC3, DCDC4, LDO1)
Deglitch (output falling) N/A 1 ms
Deglitch (output rising) N/A 50 µs

The following rules apply to the PGOOD output:

  • The power-up default state for PGOOD is low. When all rails are disabled, PGOOD output is driven low.
  • Only enabled rails are monitored. Disabled rails are ignored.
  • Power-good monitoring of a particular rail starts 5 ms after the rail is enabled and is continuously monitored thereafter. This allows the rail to power-up.
  • PGOOD is delayed by PGDLY time after the sequencer is finished and the last rail is enabled.
  • If an enabled rail is continuously outside the monitoring threshold for longer than the deglitch time, PGOOD is pulled low, and all rails are shut-down following the power-down sequence. PGDLY does not apply.
  • Disabling a rail manually by resetting the DCx_EN or LDO1_EN bit has no effect on the PGOOD pin. If all rails are disabled, PGOOD is driven low as the last rail is disabled.
  • If the power-down sequencer is triggered, PGOOD is driven low.
  • PGOOD is driven low in SUSPEND state, regardless of the number of rails that are enabled.

Figure 4-8 shows a typical power-up sequence and PGOOD timing.
