Technical Data
1.0 A 6.8 V H-Bridge Motor
Driver IC
The 17511 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 17511 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 (PWMed) 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 17511 has four operating modes: Forward, Reverse, Brake, and
Tri-state (high-impedance).
Features
• 2.0 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 logic inputs
• PWM frequencies up to 200 kHz
• Undervoltage shutdown
• Low power consumption
• Integrated charge pump
• Shoot-through current protection
• External MOSFET control circuit
