17559 SIMPLIFIED APPLICATION DIAGRAM
DESCRIPTION
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.
