Technical Data
1.0 A 6.8 V H-Bridge Motor
Driver IC
The 17511A is a monolithic H-Bridge designed to be used in
portable electronic applications to control small DC motors or bipolar
step motors. End applications include head positioners (CDROM or
disk drive), camera focus motors, and camera shutter solenoids.
The 17511A can operate efficiently with supply voltages as low as
2.0 V to as high as 6.8 V. Its low RDS(ON) H-Bridge output MOSFETs
(0.46 Ω typical) can provide continuos motor 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 V- compatible logic. The device
can be pulse width modulated (PWM-ed) at up to 200 kHz.
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 17511A 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 < 600 mΩ RDS(ON) @ 25°C Guaranteed
• 3.0 V/5.0 V TTL-/CMOS-Compatible Inputs
• PWM Frequencies up to 200 kHz
• Undervoltage Shutdown
•www.DataSheet4U.com Cross-Conduction Suppression
• Low Power Consumption
• Pb-Free Packaging Designated by Suffix Codes EV and EP

Notes
1. TA = 25°C, 10 ms pulse width at 200 ms intervals.
2. ESD1 testing is performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 Ω), ESD2 testing is performed in
accordance with the Machine Model (CZAP = 200 pF, RZAP = 0 Ω).
3. 37 x 50 x 1.6 [mm] glass EPOXY board mount.
4. Maximum at TA = 25°C.
5. Soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
6. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
7. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL),
Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e.
MC33xxxD enter 33xxx), and review parametrics.

TYPICAL APPLICATIONS
FUNCTIONAL PIN DESCRIPTION
TYPICAL APPLICATIONS
Figure 7 shows a typical application for the 17511A. When
applying the gate voltage to the CRES pin from an external
source, be sure to connect it via a resistor equal to, or greater
than, RG = VCRES/0.02 Ω.

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 via placing a capacitor or zener at the
supply pin (VM) (see Figure 8).
