3 Description
The MCT8315A provides a single-chip, codefree
sensorless trapezoidal solution for customers
requiring high speed operation (up to 3 kHz electrical)
or very fast start-up time (< 50 ms) for 12- to 24-V
brushless-DC motors requiring up to 4-A peak current.
The MCT8315A integrates three ½-bridges with 40-
V absolute maximum capability and a low RDS(ON)
of 240 mΩ (high-side + low-side FETs). MCT8315A
integrates power management circuits including an
voltage-adjustable buck regulator (3.3 V / 5 V, 170-
mA) and LDO (3.3 V, 20 mA) that can be used to
power external circuits.
Sensorless trapezoidal control is highly configurable
(motor start-up/stop behavior, fault handling, closed
loop operation) through register settings in a nonvolatile
EEPROM, which allows the device to operate
stand-alone once it has been configured. The
MCT8315A receives a speed command through
a PWM signal, analog voltage, variable frequency
square wave or I2C instruction. There are a large
number of protection features integrated into the
MCT8315A to protect the device, motor, and system
against fault events.
