•
•
The MTS62C19A motor driver is a CMOS device capable of driving both windings of a bipolar stepper motor
or bidirectionally control two DC motors. Each of the
two independent H-bridge outputs is capable of sustaining 40V and delivering up to 750 mA of continuous
current. The output current level is controlled by an
internal pulse-width modulation (PWM) circuit that is
configured using two logic inputs, a current sense
resistor, and a selectable reference voltage. The
H-bridge outputs have been optimized to provide a low
output saturation voltage drop.

Note:
The MTS62C19A device is formerly a
product of Advanced Silicon.
Full, half and micro-stepping operations are possible
with the PWM current control and logic inputs. The
maximum output current is set by a sensing resistor
and a user-selectable reference voltage. The output
current limit is selected using two logic level inputs. The
selectable output current limits are 0%, 33%, 67% or
100% of the maximum output current. Each bridge has
a PHASE input signal which is used to control the
direction of current flow through the H-bridge and the
load.
The H-bridge power stage is controlled by non-overlapping signals which prevent current cross conduction
when switching the direction of the current flow. Internal
clamp diodes protect against inductive transients.
Thermal protection circuitry disables the outputs when
the junction temperature exceeds the safe operating
limit. No special power-up sequencing is required.
Undervoltage Lockout circuitry prevents the chip from
operating when the load supply is applied prior to the
logic supply.
The device is supplied in a 24-pin SOP Package.

FUNCTIONAL DESCRIPTION
3.1
Each motor winding is driven by an H-type bridge
consisting of two N and two P transistors that allow the
current to flow in both winding directions depending on
the value of the PHASE signal (Table 3-1). The
H-bridge can be set in five configurations that are
related to the digital inputs PHASE, I0 and I1 and to the
current sensed. These configurations are shown in
Table 3-2.
The circuit is designed to drive the two windings of a
bipolar stepper motor, and can be divided in two identical channels (channel 1 and channel 2) and protection
circuitry for overtemperature and undervoltage. The
functionality of a channel and protection circuitry is
presented in the following sections.

PWM Current Control
The current level in each motor winding is controlled by
a PWM circuit with a fixed TOFF time. The load current
flowing in the winding is sensed through an external
sensing resistor RS, connected between the power
bridge's source pin SENSE (sources of transistors Na
and Nb) and GND.

PWM Current Control Circuit Principle (Channel 1 Shown).
The voltage across RS is compared to a fraction of the
reference voltage VREF, chosen with the logic input bits
I0 and I1 (Table 3-3). The power bridge, and thus the
load current, can also be switched off completely when
both logic inputs are high. Note that any logic input left
unconnected will be treated as a high level (pull-up
resistor).

When the maximum allowed current is reached, the
bridge source is turned off during a fixed period TOFF
(typically 50 µs) given by a non-retriggerable pulse
generator and the external timing components Rt
(20k – 100 k range) and Ct (100 pF – 1000 pF
range):
EQUATION 3-2:
3.3
A thermal protection circuitry turns off all drivers when
the junction temperature exceeds a safe operating limit
of +170°C (typical). This protects the devices from
failure due to excessive heating. Despite this thermal
protection, output short circuits are not permitted. The
output drivers are re-enabled once junction
temperature has dropped below +145°C (typical).
T OFF = 1.1   R t  C t 
During TOFF the winding current decreases. When the
driver is re-enabled, the winding current increases
again until it reaches the threshold, and the cycle
repeats itself, maintaining the load current at the
desired level.

An undervoltage lockout circuit protects the
MTS62C19A from potential shoot-through currents
when the load supply voltage is applied prior to the
logic supply voltage. The power bridge and all outputs
are disabled if VLOGIC is smaller than 4V.
With this protection feature, the circuit will withstand
any order of turn-on or turn-off of the supply voltages
VLOGIC and VLOAD. Normal dV/dt values are assumed.

Typical Application Circuit.
During PWM operation, when the output stage is
turned-on, large voltage peaks might appear across
RS, which can wrongly trigger the input comparator. To
avoid an unstable current control, an external RCCC filter should be used that delays the comparator action.
Depending on load type, many applications will not
require this filter (SENSE connected to COMPIN).

PCB Design Guidelines
Unused inputs should be connected to fixed voltage
levels in order to get the highest noise immunity. Typical PCB layout guidelines for power applications
should be followed. These include separate power
ground planes, supply decoupling capacitors close to
the IC, short connections and use of maximized copper
areas to improve thermal dissipation.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
