package it is idealy suited for controlling DC motors.
When used for DC motor control it performs
the power stage required for both speed and direction
control. The device can be combined with
a current regulator like the L6506 to implement a
transconductance amplifier for speed control, as
shown in figure. In this particular configuration
only half of the L6506 is used and the other half
of the device may be used to control a second
motor
The L6506 senses the voltage across the sense
resistor RS to monitor the motor current: it compares
the sensed voltage both to control the
speed and during the brake of the motor.

DESCRIPTIONThe I.C. is a full bridge driver for motor control applications
realized in Multipower-BCD technology
which combines isolated DMOS power transistors
with CMOS and Bipolar circuits on the same chip.
By using mixed technology it has been possible to
optimize the logic circuitry and the power stage to
achieve the best possible performance. The
DMOS output transistors can operate at supply
voltages up to 42V and efficiently at high switching
speeds. All the logic inputs are TTL, CMOS
and C compatible. Each channel (half-bridge) of
the device is controlled by a separate logic input,
while a common enable controls both channels.
The I.C. is mounted in three different packages.
Freture- SUPPLY VOLTAGE UP TO 48V
- 5A MAX PEAK CURRENT (2A max. for L6201)
- TOTAL RMS CURRENT UP TO
- L6201: 1A; L6202: 1.5A; L6203/L6201PS: 4A
- RDS (ON) 0.3 (typical value at 25 C)
- CROSS CONDUCTION PROTECTION
- TTL COMPATIBLE DRIVE
- OPERATING FREQUENCY UP TO 100 KHz
- THERMAL SHUTDOWN
- INTERNAL LOGIC SUPPLY
- HIGH EFFICIENCY
