Functional Description
The G526-1 and G526-2 are dual high-side switches
with active-high and active-low enable inputs, respec-
tively. Fault conditions turn off or inhibit turn-on one or
both of the output transistors, depending upon the
type of fault, and activate the open-drain error flag
transistors to pull FLG pin to ground.
Input and Output
IN (input) is the power supply connection to the logic
circuitry and the source of the output MOSFET. OUTx
(output) is the drain of the output A or B MOSFET. In a
typical circuit, current flows through the switch from IN
to OUT toward the load.
The output MOSFET and driver circuitry are also de-
signed to allow the MOSFET drain to be externally
forced to a higher voltage than the source (V
OUT
> V
IN
)
when the output is off. In this situation, the G526
avoids undesirable drain-to-body diode current flow by
connecting the body to the most positive voltage. If
V
OUT
>V
IN
when switch is enabled, current will flow
from V
OUT
to V
IN
.
Thermal Shutdown
Thermal shutdown shuts off both output MOSFETs
and signals both fault flags if the die temperature ex-
ceeds 135°C. 10°C of hystersis prevents the switch
from turning on until the die temperature drops to
125°C. Overtemperature detection functions only
when at least one switch is enabled.
