AMIS−42673
Definitions
All voltages are referenced to GND (Pin 2). Positive currents flow into the IC. Sinking current means that the current is
flowing into the pin. Sourcing current means that the current is flowing out of the pin.
Table 6. DC CHARACTERISTICS V_CC = 4.75 V to 5.25 V, V₃₃ = 2.9 V to 3.6 V; T_J = −40°C to +150°C; R_LT = 60 W unless specified
otherwise.
