ELECTRICAL CHARACTERISTICS (continued)
(AGND = +48V. V
values are at AGND = +48V, DGND = +48V, V
negative otherwise.)
Note 1: GATE_ is internally clamped to 11.4V above V
Note 2: Default values. The charge/discharge currents are programmable through the serial interface (see the
Note 3: Default values. The current-limit thresholds are programmed through the I
Note 4: This is the default value. Threshold can be programmed through serial interface R23h[2:0].
Note 5: AC disconnect works only if V
Note 6: t
Note 7: R
Note 8: Default values. The startup and fault times can be also programmed through the I
Note 9: Guaranteed by design. Not subject to production testing.
(V
all registers = default setting, unless otherwise noted.)
