3 Description
The MCF8315C provides a single-chip, code-free
sensorless FOC solution for customers driving speedcontrolled
12- to 24-V brushless-DC motors (BLDC)
or Permanent Magnet Synchronous motor (PMSM) up
to 4-A peak current. The MCF8315C integrates three
?-bridges with 40-V absolute maximum capability and
a low RDS(ON) of 250/265 mΩ (high-side + low-side
FETs). MCF8315C 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.
The FOC algorithm configuration can be stored in
non-volatile EEPROM, which allows the device to
operate stand-alone once it has been configured.
The device receives a speed command through a
PWM input, analog voltage, variable frequency square
wave or I2C command. There are a large number
of protection features integrated into the MCF8315C,
intended to protect the device, motor, and system
against fault events.
MCF8315C is available in two packages - 32-pin
6x4mm QFN (RRY) and 24-pin 7.x8x6.4mm HTSSOP
(PWP)
