ELECTRICAL CHARACTERISTICS (continued)

(VCC, IN1–IN4 = +2.7V to +5.5V; ENABLE = MARGIN = MR = ABP = TRKEN; TA = -40°C to +85°C, unless otherwise specified.

Typical values are at TA = +25°C.) (Note 1)

Note 5: The MAX6876 programmed as a single device; GATE timeout has counted prior to beginning each sequence of power-up.

GATE timeout is not enabled during power-down or when the device is programmed as a master/slave.

Note 6: The MAX6876 programmed as a single device, the autoretry time begins to count at the assertion of the FAULT signal.

The MAX6876 programmed as a master/slave device; the autoretry time begins to count at the deassertion of the

common FAULT signal.
