Then:
(V
EEUV(on)) = 1.22 x (R1+R2+R3)/(R2+R3)
(V
EEUV(on)) = 1.22 x (487k+6.65k+9.31k)/(6.65k+9.31k)
= 38.45V
And:
(V
EEOV(on)) = 1.12 x (R1+R2+R3)/R3
(V
EEOV(on)) = 1.12 x (487kΩ +6.65kΩ +9.31kΩ)/9.31kΩ
= 60.51V
Therefore, the circuit will start when the input supply voltage
is in the range of 38.45V to 60.51V.
Undervoltage/Overvoltage Protection
t
PWRGD-A is the time delay from VEEUV(on) to PWRGD-A going
active. It can be approximated by:
t
PWRGD-A = CRAMP x (VINT-1.17)/IRAMP
where:
C
RAMP = capacitor connected from RAMP pin to VEE pin
V
INT = internal regulated power supply voltage (10V typ.)
I
RAMP = 10A charge current
PWRGD Flags Delay Programming
When the ramp voltage hits V
INT - 1.17V, PWRGD-A be-
comes active indicating that the input supply voltage is within
the programmed limits. PWRGD-B goes active after a pro-
grammed time delay after PWRGD-A went active. PWRGD-
C goes active after a programmed time delay after PWRGD-
B went active. PWRGD-D goes active after a programmed
time delay after PWRGD-C went active.
The resistors connected from TB, TC, and TD to VEE pin
determines the delay times between the PWRGD ags.
The value of the resistors determines the capacitor charging
and discharging current of a triangular wave oscillator. The
oscillator output is fed into an 8-bit counter to generate the
desired time delay.
The respective time delay is dened by the following equa-
tion:
t
TX = (255 x 2 x COSC x VPP)/ICD
and
I
CD = VBG / (4 x RTX)
Where:
t
TX = Time delay between respective PWRGD ags
C
OSC = 120pF (internal oscillator capacitor)
V
PP = 8.2V (peak-to-peak voltage swing of oscillator)
I
CD = Charge and discharge current of oscillator
V
BG = 1.17V (internal band gap reference)
R
TX = Programming resistor at TB, TC, or TD
Combining the two equations and solving for R
TX yields:
R
TX = (VBG x tTX) / (2040 x COSC x VPP)
= 0.585 x 106 x t
TX
For a time delay of 200ms
R
TX
= 0.585 x 106 x 0.2 = 117kΩ
For a time delay of 5ms
R
TX
= 0.585 x 106 x 0.005 = 2.925kΩ
