ELECTRICAL CHARACTERISTICS (continued)
(VAGND = 32V to 60V, VEE = 0V, VDD to VDGND = +3.3V, all voltages are referenced to VEE, unless otherwise noted. Typical values are at
VAGND = +48V, VDGND = +48V, VDD = (VDGND + 3.3V), TA = +25°C. Currents are positive when entering the pin and negative other-
wise.) (Note 2)

Note 2:
Limits to TA = -40°C are guaranteed by design.
Note 3:
Default values. The charge/discharge currents are programmable through the serial interface (see the
Register Map and
Description section).
Note 4:
Default values. The current-limit thresholds are programmed through the I2C-compatible serial interface (see the
Register
Map and Description section).
Note 5:
Functional test is performed over thermal shutdown entering test mode.
Note 6:
This is the default value. Threshold can be programmed through serial interface R23h[2:0].
Note 7:
AC disconnect works only if (VDD - VDGND) ≥ 3V and DGND is connected to AGND.
Note 8:tDISC can also be programmed through the serial interface (R16h) (see the Register Map and Description section).
Note 9:
RD = (VOUT2 - VOUT1)/(IDET2 - IDET1). VOUT1, VOUT2, IDET2, and IDET1 represent the voltage at OUT_ and the current at
DET_ during phase 1 and 2 of the detection.
Note 10: Default values. The startup and fault times can also be programmed through the I2C serial interface (see the
Register Map
and Description section).
