MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
17550

SYSTEM/APPLICATION INFORMATION
INTRODUCTION
The 17550 is a monolithic quad H-Bridge ideal for portable
electronic applications containing multiple bipolar step motors
and/or brush DC motors. The device features an on-board DC/
DC converter to provide gate-drive voltages, as well as level-
shifting circuitry. The control logic translates the input signals
to the gate-driver circuitry while providing cross-conduction
suppression.
The 17550 has four operating modes: Forward, Reverse,
Brake, and Tri-Stated (High Impedance). The MOSFETs
comprising the output bridge have a total source+sink R
DS(ON)
≤
1.2
.
The 17550 can simultaneously drive four brush DC motors
or two bipolar step motors. The drivers are designed to be
PWM’ed at frequencies up to 200 kHz.
FUNCTIONAL TERMINAL DESCRIPTION
V
DD
The V
DD
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.
INAF, INAR, INBF, INBR, INCF, INCR, INDF, INDR
These logic input terminals control each H-Bridge output;
e.g., IN*F logic HIGH = HB*F HIGH; likewise, IN*R logic HIGH
= HB*R HIGH. However, if both “F” and “R” inputs are taken
HIGH, the associated bridge’s outputs are both tri-stated (refer
to
Table 1, Truth Table
, page 8).
OE
OE
terminal is a LOW = TRUE enable input. When
OE
= HIGH, all H-Bridge outputs are tri-stated (high
impedance) regardless of logic inputs states.
HBAF, HBAR, HBBF, HBBR, HBCF, HBCR, HBDF,
HBDR
These terminals provide connection to the outputs of each
of the internal H-Bridges (see
Figure 1, 17550 Simplified
Internal Block Diagram
, page 2).
VM
The VM terminals carry the main supply voltage and current
into the power sections of the 17550. This supply then
becomes controlled and/or modulated by the 17550 as it
delivers the power to the loads attached between the H-Bridge
output terminals. All VM terminals must be connected together
on the printed circuit board.
LX
The LX terminal is the open-drain output of the internal DC/
DC converter circuit. It is the junction for the external inductor
and the anode of the external Schottky diode.
VG
The VG terminal is the input terminal for the gate-drive
voltage. It can be supplied from the built-in DC/DC converter
or from an external source.
Ground Terminals
All ground terminals must be tied together on the PCB.
