MP6505
4.5V-to-16V,400mA, Single-Phase
Brushless-DC–Motor Driver
The Future of Analog IC Technology
DESCRIPTION
The MP6505 is a single-phase brushless-DC–
motor driver, with an input voltage range of 4.5V
to 16V and a maximum output current of 400mA.
The MP6505 controls the rotational speed
through either the input voltage or the PWM
signal. Other features include minimum-
rotational–speed set, a rotational speed indicator,
built-in input over-voltage protection, built-in
locked-rotor
protection,
locked-rotor–state
indicator, thermal shutdown, and a 1.2V
integrated Hall bias voltage.
The MP6505 is available in 5.0mm×6.4mm
TSSOP16 and 3mm×3mm QFN16 package.
