SYSTEM/APPLICATION INFORMATION
INTRODUCTION
The 17517 is a triple totem-pole output H-Bridge power IC
designed to drive small dc motors used in portable electronics.
The 17517 can operate efficiently with supply voltages as low
as 2.0 V to as high as 6.8 V, and provide continuos motor drive
currents of 1.0 A while handling peak currents up to 3.0 A. It is
easily interfaced to low cost MCUs via parallel 3.0 V- or 5.0 V-
compatible logic. The device can be pulse width modulated
(PWM-ed) at up to 200 kHz. The 17517 can drive two motors in
two directions one at a time; or it can drive one motor in two
directions and one solenoid with synchronous rectification of
freewheeling currents one at a time. Two-motor operation is
accomplished by hooking one motor between OUTA and
OUTB, and the other motor between OUTB and OUTC.
Motor + solenoid operation is accomplished by hooking a motor
between OUTA and OUTB and placing a solenoid between
OUTC and GND.
Table 1, Truth Table
, page 8, describes the
operating states versus the input conditions.
As shown in
Figure 1, 17517 Simplified Internal Block
Diagram
, page 2, the 17517 is a monolithic triple totem-pole
output bridge with built-in charge pump circuitry. Each of the six
MOSFETs forming the triple totem-pole output has an R
DS(ON)
of
≤
0.6
(guaranteed by design). The IC has an integrated
charge pump and level shifter (for gate drive voltages).
Additionally, the IC has a built-in shoot-through current
protection circuit and undervoltage lockout function. This IC has
four operating modes: Forward, Reverse, Brake, and Tri-Stated
(High Impedance).
FUNCTIONAL TERMINAL DESCRIPTION
OUTA, OUTB, and OUTC
These terminals provide the connection to the internal power
MOSFET triple-totem-pole H-bridge of the IC.
GND
Power and signal ground terminal.
C
RES
This 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 V
DDRES
voltage is used by the IC to
supply gate drive for the internal power MOSFETs.
VM
The two 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 OUTA and OUTB.
The 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.
IN1, IN1, EN1, and EN2
These terminals are input control terminals used to control
the outputs. These terminals are 3.0 V/5.0 V CMOS-compatible
inputs with hysteresis. These terminals work together to control
OUTA, OUTB, and OUTC (refer to
Table 1, Truth Table
).
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
μ
F.
V
DD
This terminal carries the logic supply voltage and current into
the logic sections of the IC. V
DD
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.
