Voltage-Tracking Controllers for
PowerPC, DSPs, and ASICs
Programming I/O_SENSE Voltage
4) Calculate using the following equation:
R 5 = ?
V I / O _ REF
?
? 1 ? R 6

(MAX5040 Only)
See the application circuit examples in Figures 9 and 10.
I/O_SENSE is used to monitor the I/O output voltage or
any other voltage. The result is reported by the POK out-

R 5 = ? I / O _ SENSENOM ? 1 ? R 6
put signal. Choose the I/O_SENSE trip point such that
the minimum monitored voltage at I/O_SENSE exceeds
the maximum I/O_SENSE rising threshold.
Follow the guidelines below to program the I/O_SENSE
voltage:
1) Determine the tolerance of the output voltage to be
monitored, V O : 5% is common.
where R6 is typically 10k ? .
Example: V I/O nominal value = 3.3V, set V I/O_SENSE
nominal value to 3.3V - (5% + 6.6%) = 2.9172V.
Choose R6 = 10.0k ? , 1%:
? V ?

? V / O _ REF ?
R 5 = ?
? 1 ? 10 k ? = 13 . 72 k ?
2) Determine V I/O_SENSE rising threshold tolerance:
I/O sense trip-point threshold, V IO_REF , tolerance:
1.230V ±2.5%
? 2 . 9172 V
? 1 . 230 V
?
?
Resistor error tolerance build-up is the same as that
calculated in the Programming UVLO Voltage sec-
tion.
Total = ±6.6%.
3) Set V I/O_SENSE rising nominal value to: V O nominal
value - (V O tolerance + V I/O_SENSE tolerance).
Use the next lower 13.7k ? standard value.
Calculating Component Values
For more detailed information, go to Maxim’s website
for the Application Note, "Dual Voltage Tracking Circuit
for I/O, Microprocessor, and DSP Core Voltages." A link
in the application note has a downloadable component
selection spreadsheet for calculating component val-
ues. This spreadsheet calculates values for all passive
components in Figure 10 and lists the resulting
min/max values of V REGNOM for standard PowerPC
core voltages. DIY options are included for other core
and I/O voltages.
