MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
SYSTEM/APPLICATION INFORMATION
INTRODUCTION
The 17510 is a monolithic H-Bridge power IC applicable to
small DC motors used in portable electronics. The 17510 can
operate efficiently with supply voltages as low as 2.0 V to as
high as 15 V, and it can provide continuos motor drive currents
of 1.2 A while handling peak currents up to 3.8 A. It is easily
interfaced to low-cost MCUs via parallel 5.0 V-compatible logic.
The device can be pulse width modulated (PWM-ed) at up to
200 kHz. The 17510 has four operating modes: Forward,
Reverse, Brake, and Tri-Stated (High Impedance).
Basic protection and operational features (direction, dynamic
braking, PWM control of speed and torque, main power supply
undervoltage detection and shutdown, logic power supply
undervoltage detection and shutdown), in addition to the 1.0 A
rms output current capability, make the 17510 a very attractive,
cost-effective solution for controlling a broad range of small DC
motors. In addition, a pair of 17510 devices can be used to
control bipolar stepper motors. The 17510 can also be used to
excite transformer primary windings with a switched square
wave to produce secondary winding AC currents.
As shown in
Figure 1, 17510 Simplified Internal Block
Diagram
, page 2, the 17510 is a monolithic H-Bridge with built-
in charge pump circuitry. For a DC motor to run, the input
conditions need to be set as follows: ENable input logic HIGH,
one INput logic LOW, and the other INput logic HIGH (to define
output polarity). The 17510 can execute dynamic braking by
setting both IN1 and IN2 logic HIGH, causing both low-side
MOSFETs in the output H-Bridge to turn ON. Dynamic braking
can also implemented by taking the ENable logic LOW. The
output of the H-Bridge can be set to an open-circuit high-
impedance (Z) condition by taking both IN1 and IN2 logic LOW.
(refer to
Table 1, Truth Table
, page 7).
The 17510 outputs are capable of providing a continuous DC
load current of up to 1.2 A. An internal charge pump supports
PWM frequencies to 200 kHz. The EN terminal also controls the
charge pump, turning it off when EN = LOW, thus allowing the
17510 to be placed in a power-conserving sleep mode.
FUNCTIONAL TERMINAL DESCRIPTION
OUT1 and OUT2
The OUT1 and OUT2 terminals provide the connection to the
internal power MOSFET H-Bridge of the IC. A typical load
connected between these terminals would be a small DC motor.
These outputs will connect to either VM or PGND, depending
on the states of the control inputs (refer to
Table 1, Truth Table
,
page 7).
PGND and LGND
The power and logic ground terminals (PGND and LGND)
should be connected together with a very low-impedance
connection.
C
RES
The C
RES
terminal provides the connection for the external
reservoir capacitor (output of the charge pump). Alternatively
this terminal can also be used as an input to supply gate-drive
voltage from an external source via a series current-limiting
resistor. The voltage at the C
RES
terminal will be approximately
three times the V
DD
voltage, as the internal charge pump
utilizes a voltage tripler circuit. The
VC
RES
voltage is used by
the IC to supply gate drive for the internal power MOSFET
H-Bridge.
VM
The VM terminals carry the main supply voltage and current
into the power sections of the IC. This supply then becomes
controlled and/or modulated by the IC as it delivers the power
to the load attached between OUT1 and OUT2. All VM
terminals must be connected together on the printed circuit
board with as short as possible traces offering as low
impedance as possible between terminals.
VM has an undervoltage threshold. If the supply voltage
drops below the undervoltage threshold, the output power
stage switches to a tri-state condition. When the supply voltage
returns to a level that is above the threshold, the power stage
automatically resumes normal operation according to the
established condition of the input terminals.
IN1, IN2, and EN
The IN1, IN2, and EN terminals are input control terminals
used to control the outputs. These terminals are 5.0 V CMOS-
compatible inputs with hysteresis. The IN1, IN2, and EN work
together to control OUT1 and OUT2 (refer to
Table 1, Truth
Table
).
GIN
The
GIN
input controls the GOUT terminal. When
GIN
is set
logic LOW, GOUT supplies a level-shifted high-side gate drive
signal to an external MOSFET. When
GIN
is set logic HIGH,
GOUT is set to GND potential.
C1L and C1H, C2L and C2H
These two pairs of terminals, the C1L and C1H and the C2L
and C2H, connect to the external bucket capacitors required by
the internal charge pump. The typical value for the bucket
capacitors is 0.1
