SEMICONDUCTOR TECHNICAL DATA
1.0 A 6.8 V Dual Motor Driver IC
The 17517 is a monolithic triple totem-pole-output power IC designed to be used in portable electronic applications to control small DC motors and solenoids. The 17517 can operate efficiently with supply voltages as low as
2.0 V to as high as 6.8 V. Its low R typical) can provide continuos drive currents of 1.0 A and handle peak currents
up to 3.0 A. It is easily interfaced to low-cost MCUs via parallel 3.0 V- or 5.0 V­compatible 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 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 hooking the other motor between OUTB and OUTC. Motor plus solenoid operation is accomplished by hooking a motor between OUTA and OUTB and a solenoid between OUTC and GND.
This device contains an integrated charge pump and level shifter (for gate drive voltages), integrated shoot-through current protection (cross-conduction suppression logic and timing), and undervoltage detection and shutdown circuitry.
The 17517 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance).
Features
• 2.0 V to 6.8 V Continuous Operation
• Output Current 1.0 A (DC), 3.0 A (Peak)
•MOSFETs < 600mΩ R

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.

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
times the V voltage tripler circuit. The V 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.

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
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).
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,
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 µF.

DD
This terminal carries the logic supply voltage and current into the logic sections of the IC. V
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.

CEMF Snubbing Techniques
Care must be taken to protect the IC from potentially damaging CEMF spikes induced when commutating currents in inductive loads. Typical practice is to provide snubbing of voltage transients by placing a capacitor or zener at the supply terminal (VM) (see Figure 6
