Typical input voltage range of 3 to 5.5 V
Adjustable constant voltage or PWM operation
Less than 500 nA standby mode current
–40 to 85 operating temperature range
The A3908 is a low voltage bidirectional DC motor driver with
a typical input voltage range of 3 to 5.5 V and output currents up
to 500 mA. The unique output full-bridge incorporates source-
side linear operation to allow a constant voltage across the motor
coil. This regulated output minimizes motor voltage change due
to I × R DS(on) variation and battery voltage tolerance.
Logic input pins are provided to control the motor direction of
rotation, brake, and standby (< 500 nA supply current) modes and
to allow optional PWM of the sink drivers. Internal protection
circuitry includes thermal shutdown, undervoltage lockout, and
crossover current (shoot-through) protection.
The A3908 is supplied in a 2 mm x 2 mm, 0.55 mm nominal
height, 8-lead DFN package, with exposed thermal pad (package
suffix EE). This small footprint package is lead (Pb) free, with
Package: 8 Contact DFN (suffix EE)
100% matte tin leadframe plating.
