FUNCTIONAL DEVICE OPERATION
FUNCTIONAL PIN DESCRIPTION
FUNCTIONAL DEVICE OPERATION
SHORT-CIRCUIT PROTECTION
If an output short-circuit condition is detected, the power
outputs tri-state (latch-OFF) independent of the input (IN1
and IN2) states, and the fault status output flag is set logic
Low. If the D1 input changes from logic High to logic Low, or
if the D2 input changes from logic Low to logic High, the
output bridge will become operational again and the fault
status flag will be reset (cleared) to a logic High state.
The output stage will always switch into the mode defined by
the input pins (IN1, IN2, D1, and D2), provided the device
junction temperature is within the specified operating
temperature.
ACTIVE CURRENT LIMITING
The maximum current flow under normal operating
conditions is internally limited to I LIM (5.2 A to 7.8 A). When
the maximum current value is reached, the output stages are
tri-stated for a fixed time (t a ) of 20 ? s typical. Depending on
the time constant associated with the load characteristics, the
current decreases during the tri-state duration until the next
output ON cycle occurs (see Figures 9 and 12 , page 10 and
The current limiting threshold value is dependent upon the
device junction temperature. When -40 ? C < T J < 160 ? C, I LIM
is between 5.2 A and 7.8 A. When T J exceeds 160 ? C, the
I LIM current decreases linearly down to 2.5 A typical at
175 ? C. Above 175 ? C the device overtemperature circuit
detects T LIM and overtemperature shutdown occurs (see
operational for a longer time but at a regressing output
performance level at junction temperatures above 160 ? C.
OVERTEMPERATURE SHUTDOWN AND
HYSTERESIS
If an overtemperature condition occurs, the power outputs
are tri-state (latched-OFF) independent of the input signals
and the fault status flag is set logic Low.
To reset from this condition, D1 must change from logic High
to logic Low, or D2 must change from logic Low to logic High.
When reset, the output stage switches ON again, provided
that the junction temperature is now below the
overtemperature threshold limit minus the hysteresis.
Note Resetting from the fault condition will clear the fault
status flag.
MAIN DIFFERENCES COMPARED TO
MC33186DH1
? COD pin has been removed. Pin 8 is now a Do Not
Connect (DNC) pin.
? Pin 20 is no longer connected in the 20 HSOP package. It
is now a DNC pin.
? R DS(ON) max at T J = 150 °C is now 225 m ? per each
output transistor.
? Maximum temperature operation is now 160 °C, as
minimum thermal shutdown temperature has increased.
? Current regulation limiting foldback is implemented above
160 °C T J .
? Thermal resistance junction to case has been increased
from ~2.0 °C/W to ~5.0 °C/W.
