CIRCUIT DESCRIPTION

The L6201/1PS/2/3 is a monolithic full bridge
switching motor driver realized in the new Mul­tipower-BCD technology which allows the integra­tion of multiple, isolated DMOS power transistors
plus mixed CMOS/bipolar control circuits. In this
way it has been possible to make all the control
inputs TTL, CMOS and µC compatible and elimi­nate the necessity of external MOS drive compo­nents. TheLogicDrive is shownin table 1.

Although the device guarantees the absence of
cross-conduction,the presenceof the intrinsicdi­odes in the POWER DMOS structure causes the
generation of current spikeson thesensing termi­nals. This is due to charge-dischargephenomena
in the capacitors C1 & C2 associated with the
drain source junctions (fig. 14). When the output
switches from high to low, a current spike is gen­erated associated with the capacitor C1. On the
low-to-high transitiona spike of the same polarity
is generated by C2, preceded by a spike of the
opposite polarity due to the charging of the input
capacity of the lower POWER DMOS transistor
(fig. 15).

Transitions

As already seen above the transistors have an in­trinsic diode between their source and drain that
can operate as a fast freewheeling diode in
switched mode applications. During recirculation
with the ENABLE input high, the voltage drop
across the transistor is R

Boostrap Capacitors

To ensurethat the POWERDMOS transistorsare
driven correctly gate to source voltage of typ. 10
V must be guaranteed for all of the N-channel
DMOS transistors.This is easy to be provided for
the lower POWER DMOS transistors as their
sources are refered to ground but a gate voltage
greater than the supply voltage is necessary to
drive the upper transistors.This is achievedby an
internal charge pump circuit that guarantees cor­rect DC drive in combinationwith the boostrap cir­cuit. For efficient charging the value of the boos­trap capacitor should be greater than the input
capacitance of the power transistor which is
around 1 nF. It is recommended that a capaci­tance of at least 10 nF is used for the bootstrap.If
a smallercapacitor is used there is a risk that the
POWER transistors will not be fully turned on and
they will show a higher RDS (ON). On the other
hand if a elevated value is used it is possible that
a currentspike may be producedin the sense re­sistor.

Reference Voltage

To by-pass the internal Ref. Volt. circuit it is rec­ommendedthat a capacitorbe placed betweenits
pin and ground.A value of 0.22 µF should be suf­ficient for most applications. This pin is also pro­tected against a short circuit to ground: a max.
current of 2mA max.can be sinkedout.

Dead Time

To protect the device against simultaneous con­duction in both arms of the bridge resulting in a
rail to rail short circuit, the integrated logic control
provides a dead time greaterthan 40 ns.

Thermal Protection

A thermal protection circuit has been included
that will disable the deviceif the junction tempera­ture reaches150 °C. When the temperature has
fallen to a safe level the device restarts the input
and enablesignals under control.

APPLICATION INFORMATION
Recirculation

During recirculation with the ENABLE input high,
the voltage drop across the transistor is RDS
(ON)⋅ IL, clamped at a voltage depending on the
characteristics of the source-drain diode. Al­though the device is protected against cross con­duction, current spikes can appear on the current
sense pin due to charge/dischargephenomena in
the intrinsic source drain capacitances. In the ap­plication this does not cause any problem be­cause the voltage spike generated on the sense
resistoris maskedby thecurrentcontrollercircuit.

DC Motor Speed Control

Since theI.C. integratesa full H-Bridge in a single
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 combinedwith
a current regulator like the L6506 to implement a
transconductance amplifier for speed control, as
shown in figure 17. 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 R

to monitor the motor current: it com-

S

pares the sensed voltage both to control the
speedand duringthe brakeof the motor.

Betweenthe sense resistor and each sense input
of the L6506 a resistor is recommended; if the
connections between the outputs of the L6506
and the inputs of the L6203 need a long path, a
resistor must be added between each input of the
L6203 and ground.

A snubbernetwork made by the series of Rand C
must be foreseen very near to the output pins of
the I.C.; one diode (BYW98) is connected be­tween each poweroutput pinand groundas well.

The following formulas can be used to calculate
the snubber values:

R ≅ V

S/lp

C=lp/(dV/dt)where:
V

is the maximum Supply Voltage foreseen on

S

the application;

is thepeak of the loadcurrent;

I

p

dv/dt is the limited rise time of the outputvoltage
(200V/µsis generallyused).

If the Power Supply Cannot Sink Current, a suit­able large capacitor must be used and connected
near the supply pin of the L6203. Sometimes a
capacitorat pin 17 of the L6506let the application
better work. For motor current up to 2A max., the
L6202 can be used in a similar circuit configura­tion for which a typical Supply Voltage of 24V is
recommended.

BIPOLARSTEPPERMOTORSAPPLICATIONS
Bipolar stepper motors can be driven with one

L6506 or L297, two full bridge BCD drivers and
very few external components. Together these
three chips form a complete microprocessor-to­stepper motor interfaceis realized.

As shown in Fig. 18 and Fig. 19, the controller
connect directly to the two bridge BCD drivers.
External component are minimalized: an R.C. net­work to set the chopper frequency, a resistive di­vider (R1; R2) to establish the comparator refer­ence voltage and a snubber network made by R
and C in series(See DCMotor SpeedControl).

THERMAL CHARACTERISTICS

Thanks to the high efficiency of this device, often
a true heatsink is not needed or it is simply ob­tained by means of a copper side on the P.C.B.
(L6201/2).
Under heavy conditions, the L6203 needs a suit­able cooling.
By using two square copper sidesin a similarway
