Description

Input Voltage

VIN

12V

Falls within the recommended device input voltage range of 3V to 14V.

Sequence Up Threshold

10.2V

VIN rising threshold that initiates sequence UP.

Set by:

R16 = 10 kΩ

R20 = 620 Ω

Sequence Down Threshold

6V

VIN falling threshold that initiates sequence DOWN.

Set by:

R29 = 10 kΩ

R34 = 909 Ω

PULL_UP1 Voltage

1.8V

Voltage used by all ENx outputs. Falls within the recommended device input voltage range of 1.6V to 7V.

PULL_UP2 Voltage

1.8V

Voltage used by SEQ_DONE and PWRGD outputs. Falls within the recommended device input voltage range of 1.6V to 7V.

VOUT1 VON Threshold

1.64V

(91 % of 1.8V)

Rising and falling voltage thresholds where the monitored VOUT rail is considered ON or OFF, respectively.

Set by:

R21 = 60.4 kΩ

R25 = 34.8 kΩ

VOUT1 VOFF Threshold

0.19V

(11 % of 1.8V)

VOUT2 VON Threshold

1.34 V

(90 % of 1.5V)

Rising and falling voltage thresholds where the monitored VOUT rail is considered ON or OFF, respectively.

Set by:

R22 = 49.9 kΩ

R26 = 40.2 kΩ

VOUT2 VOFF Threshold

0.15 V

(10 % of 1.5V)

VOUT3 VON Threshold

0.72 V

(90 % of 0.8V)

R36 = 90.9 kΩ

VOUT4 VOFF Threshold

0.09 V

(10 % of 0.88V)

ENx Delay Time

tDLY_TMR

12.35 ms

Programmable time delay between when the condition for an ENx signal to transition is met and when the signal actually transitions.

Set by:

R11 = 619 kΩ

J16 shunted

SENSEx Regulation Timer

tREG_TMR

12.35 ms

Programmable timer that sets the amount of time SENSEx is allowed to reach the regulation threshold voltage (VTH_SENSEx, typically 599mV). If VTH_SENSEx is not reached before the timer expires, the device will sequence down.

Set by:

R14 = 619 kΩ

J20 shunted
