MTS2916A
2.0
The descriptions of the pins are listed in
TABLE 2-1:
2.1
Logic supply ground. Only the driver current flows out
of this pin; there is no high current. Minimize voltage
drops between this pin and the logic inputs.
2.2
Connect VLOGIC to the logic source voltage. Decouple
the supply with a 0.1 µF ceramic capacitor mounted
close to the VLOGIC and GND terminals.
2.3
Connect VLOAD to the motor positive voltage supply.
The motor current is supplied through this pin and the
selected output transistors.

2.4
Comparator input for current threshold detection. The
voltage across the sense resistor is fed back to this
input through the low pass filter RcCc. The power tran-
sistors are disabled when the sense voltage exceeds
the reference voltage of the selected comparator.
When this occurs the current decays for a time set by
RtCt (T
