Application
1 、 POWER OUTPUT STAGE
The XBLW GT298 integrates two power output stages (A ; B).The power output stage is a
bridge onfiguration and its outputs can drive an inductive load in common or differenzial
mode, depending on the state of the inputs.
The current that flows through the load comes out from the bridge at the sense output : an
external resistor (RSA ; RSB.) allows to detect the intensity of this current.
2 、 INPUT STAGE
All the inputs are TTL compatible
3 、 POWER
A non inductive capacitor, usually of 100 nF, must be foreseen between both Vs and Vss,
to ground, as near as possible to GND pin.The en terminal shall be in L state before the
output protection is turned off and on.
4 、 OUTPUT PROTECTION
The fast diode shall be selected as the output protection when driving inductive load.
When I = 2 A, VF ≤ 1.2V, TRR ≤ 200 ns.
5 、 PARALLEL CONNECTION
When the driving current is greater than 2A, two groups can be connected in parallel for
current expansion.
