Description
The MCP8025/6 devices are 3-phase brushless DC
(BLDC) power modules containing three integrated
half-bridge drivers capable of driving three external
NMOS/NMOS transistor pairs. The three half-bridge
drivers are capable of delivering a peak output current
of 0.5A at 12V for driving high-side and low-side NMOS
MOSFET transistors. The drivers have shoot-through,
overcurrent and short-circuit protection. A Sleep mode
has been added to achieve a typical “key-off” quiescent
current of 5 µA.
The MCP8025 device integrates a comparator, a buck
voltage regulator, two LDO regulators, power
monitoring comparators, an overtemperature sensor, a
LIN transceiver, a zero-crossing detector, a neutral
simulator and an operational amplifier for motor current
monitoring. The phase comparator and multiplexer
allow for hardware commutation detection. The neutral
simulator allows commutation detection without a
neutral tap in the motor. The buck converter is capable
of delivering 750 mW of power for powering a
companion microcontroller. The buck regulator may be
disabled if not used. The on-board 5V and 12V
low-dropout voltage regulators are capable of
delivering 30 mA of current.
The MCP8026 replaces the LIN transceiver, neutral
simulator and zero-crossing detector in MCP8025 with
two level shifters and two additional op amps.
The MCP8025/6 operation is specified over a
temperature range of -40°C to +150°C.
Package options include 40-lead 5x5 QFN and 48-lead
7x7 TQFP with Exposed Pad (EP).
