L6219DS

DUAL FULL-BRIDGE

PWM MOTOR DRIVER

The L6219DS motor driver is designed to drive both windings of a

bipolar stepper motor or bidirectionally control two dc motors. Both

bridges are capable of sustaining 45 V and include internal pulse-width

modulation (PWM) control of the output current to 750 mA. The

outputs have been optimized for a low output saturation voltage drop

(less than 1.8 V total source plus sink at 500 mA).

COMP IN

For PWM current control, the maximum output current is deter-

mined by the user’s selection of a reference voltage and sensing

resistor. Two logic-level inputs select output current limits of 0, 33,

67, or 100% of the maximum level. A PHASE input to each bridge

determines load current direction.

OUT

GROUND

The bridges include both ground clamp and flyback diodes for

protection against inductive transients. Internally generated delays

prevent cross-over currents when switching current direction. Special

power-up sequencing is not required. Thermal protection circuitry

disables the outputs if the chip temperature exceeds safe operating

limits.

DUAL FULL-BRIDGE

MOTOR DRIVER

APPLICATIONS INFORMATION

PWM OUTPUT CURRENT WAVE FORM

PWM CURRENT CONTROL

The L6219DS dual bridge is designed

to drive both windings of a bipolar stepper

motor. Output current is sensed and con-

trolled independently in each bridge by an

external sense resistor (R_S), internal com-

parator, and monostable multivibrator.

PHASE

When the bridge is turned on, current

increases in the motor winding and it is

sensed by the external sense resistor until

the sense voltage (V_COMPIN) reaches the level

set at the comparator’s input:

–

OUT

I_TRIP= V_REF/10 R_S

TRIP

The comparator then triggers the

monostable which turns off the source driver

of the bridge. The actual load current peak

will be slightly higher than the trip point

(especially for low-inductance loads) be-

cause of the internal logic and switching

delays. This delay (t_d) is typically 2 µs. After

turn-off, the motor current decays, circulating

through the ground-clamp diode and sink

transistor. The source driver’s off time (and

therefore the magnitude of the current

decrease) is determined by the monostable’s

external RC timing components, where

t_off= R_TC_Twithin the range of 20 kΩ to

100 kΩ and 100 pF to 1000 pF.

off

Dwg. WM-003-1A

LOAD CURRENT PATHS

When the source driver is re-enabled,

the winding current (the sense voltage) is

again allowed to rise to the comparator’s

threshold. This cycle repeats itself, maintain-

ing the average motor winding current at the

desired level.

Loads with high distributed capaci-

tances may result in high turn-on current

peaks. This peak (appearing across R_S)

will attempt to trip the comparator, resulting

in erroneous current control or high-fre-

quency oscillations. An external R C time

delay should be used to further del^Cay^Cthe

action of the comparator. Depending on load

type, many applications will not require these

external components (SENSE connected to

COMP IN).

MOTOR DRIVER

LOGIC CONTROL OF OUTPUT CURRENT

Two logic level inputs (l₀and I₁) allow digital selection of the motor

winding current at 100%, 67%, 33%, or 0% of the maximum level per

the table. The 0% output current condition turns off all drivers in the

bridge and can be used as an OUTPUT ENABLE function.

sequence. This is accomplished by digitally

selecting 100% drive current when only one

phase is on and 67% drive current when two

phases are on. Logic highs on both l₀and l₁

turn off all drivers to allow rapid current decay

when switching phases. This helps to ensure

proper motor operation at high step rates.

CURRENT-CONTROL TRUTH TABLE

l₀

I₁

Output Current

The logic control inputs can also be

used to select a reduced current level (and

reduced power dissipation) for ‘hold’ condi-

tions and/or increased current (and available

torque) for start-up conditions.

_REF/10 R_S= I_TRIP

V_REF/15 R_S= 2/3 I_TRIP

V_REF/30 R_S= 1/3 I_TRIP

GENERAL

These logic level inputs greatly enhance the implementation of

µP-controlled drive formats.

The PHASE input to each bridge

determines the direction motor winding

current flows. An internally generated

deadtime (approximately 2 µs) prevents

crossover currents that can occur when

switching the PHASE input.

During half-step operations, the l₀and l allow the µP to control the

motor at a constant torque between all positi¹ons in an eight-step

TYPICAL APPLICATION

All four drivers in the bridge output can

be turned off between steps (l₀= l₁≥ 2.4 V)

resulting in a fast current decay through the

internal output clamp and flyback diodes. The

fast current decay is desirable in half-step and

high-speed applications. The PHASE, l₀,and I₁

inputs float high.

STEPPER

MOTOR

Varying the reference voltage (V_REF

)

provides continuous control of the peak load

current for microstepping applications.

Thermal protection circuitry turns off all

drivers when the junction temperature

reaches +170°C. It is only intended to protect

the device from failures due to excessive

junction temperature and should not imply

that output short circuits are permitted. The

output drivers are re-enabled when the

junction temperature cools to +145°C.

FROM

µP

FROM

The L6219DS output drivers are opti-

mized for low output saturation voltages—less

than 1.8 V total (source plus sink) at 500 mA.

Under normal operating conditions, when

combined with the excellent thermal proper-

ties of the batwing package design, this

allows continuous operation of both bridges

simultaneously at 500 mA.
