Advance Information
Micromotor Driver with Dual
3-Phase and Dual H-Bridge
Outputs
The 17559 is a monolithic quad H-Bridge power IC ideal for
portable electronic applications containing multiple brushless and
brush DC-motors.
The 17559 is designed to drive motors with supplies operating
from 0.9 V to 3.5 V, with independent control of each output bridge
via parallel 1.8 V to 3.6 V logic-compatible I/O. Each output bridge
has its own gate-drive and logic circuitry with built-in shoot-through
current protection.
The 17559 has a low total R_DS(ON) of 1.7 Ω max @ 25°C for each
of the two 3-phase output bridges, and a low total R_DS(ON) of 1.3 Ω
max @ 25°C for each of the two H-Bridge outputs.
The 17559 can efficiently drive many types of micromotors owing
to its low output resistance and high output slew rates.
Features
• Two Separate Three-Phase Motor Drivers
• Two Separate H-Bridge Motor Drivers
• Low-Voltage Detection and Shutdown Circuitry
• Pb-Free Packaging Designated by Suffix Code EP
