Figure 1. Effective Differential Input Resistance/Offset Current
Note 1:
All min/max limits for the PD interface are production tested at +85
°
C (extended grade)/+70
°
C (commercial grade). Limits
at +25
°
C and -40
°
C are guaranteed by design. All PWM controller min/max limits are 100% production tested at +25
°
C
and +85
°
C (extended grade)/+70
°
C (commercial grade). Limits at -40
°
C are guaranteed by design, unless otherwise
noted.
The input offset current is illustrated in Figure 1.
Effective differential input resistance is defined as the differential resistance between GND and V
EE
without any external
resistance.
Classification current is turned off whenever the IC is in power mode.
See Table 2 in the
PD Classification Mode
section. R
DISC
and R
CL
must be 100ppm or better.
See
Thermal Dissipation section
for details.
When UVLO is connected to the midpoint of an external resistor-divider with a series resistance of 25.5k
(
±
1%), the turn-
on threshold set point for the power mode is defined by the external resistor-divider. Make sure the voltage on the UVLO
pin does not exceed its maximum rating of 8V when V
IN
is at the maximum voltage.
When the V
UVLO
is below V
TH, G, UVLO,
the MAX5941 sets the turn-on voltage threshold internally (V
UVLO,ON
).
An input voltage or V
UVLO
glitch below their respective thresholds shorter than or equal to t
OFF_DLY
does not cause the
MAX5941A/MAX5941B to exit power-on mode (as long as the input voltage remains above an operable voltage level of 12V).
