Pin Descriptions
NAME
NUMBER
DESCRIPTION
DRAIN
1
The input to the DRAIN pin senses the drain of a power MOSFET Output Motor Driver. The DRAIN volt-
age is an image of the current flowing through the power MOSFET. By limiting this voltage, the torque of
the motor can be controlled.
TRIGGER
2
The TRIGGER input is an analog voltage control level used to fix the duty-cycle at the DRAIN Output. A
voltage level here is determined by a potentiometer adjustment. The TRIGGER voltage level is com-
pared with the triangle signal from the internal oscillator to produce a pulse-width modulated signal.
GND
3
Negative pole of the battery or system ground reference.
OSC
4
Oscillator output normally terminated in a charge/discharge capacitor. A constant current is flowing in
and out to charge and discharge the external capacitor.
TORQUE
5
The TORQUE input is a reference level adjustment for torque control. The voltage reference is compared
with DRAIN input. If V
DRAIN
> V
TORQUE
, the GATE output pulse drive must be disabled.
DELAY
6
An external capacitor at the DELAY output is used to delay the torque control action. The external ca-
pacitor at the DELAY pin will start to be charged if a MOSFET output over-current condition is detected.
The purpose of the capacitor is to delay the disabling action of the signal GATE drive.
GATE
7
The GATE output drives the Gate of the Power MOSFET.
V
DD
8
Positive pole of the battery or Power Supply Voltage, nominally 7.5V.
+
NOTE: The value chosen for the torque level set pot is dependent on the type of power MOSFET and motor characteristics.
The TRIGGER is a combined SW/Speed Control function. Motor speed increases as the TRIGGER voltage decreases.
Speed control range: 2.35V (Min) < V
TRIGGER
< 5.25V (Max)
