Definition
This is the ground terminal of the device.
The Current Sense terminal delivers a ratio amount of the sum of the
high-side currents.
These are the device input terminals that directly control their associated
outputs. Each input terminal has an internal active pull-down so that the
input terminal will not float if disconnected.
Each terminal must be connected to one gate of an external low-side
MOSFET.
Terminals 5, 6, 7, and 8 are the source of the Output Channel 1 15 mΩ
high-side MOSFET1.
These terminals are not used.
Terminals 13, 14, 15, and 16 are the source of the Output Channel 2
15 mΩ high-side MOSFET2.
The status output goes low when a fault mode is detected. It is an open
drain with an internal clamp at 6.0 V. An external pull-up resistor
connected to V_DD (5.0 V) is needed.
This logic input enables control of the device. (Wake logic LOW = Sleep
Mode, Wake logic HIGH = full operation.) The WAKE terminal has a pull-
down resistor.
The backside TAB is connected to the power supply of the 33486A.
