DESCRIPTION
The AMT49107 is an N-channel power MOSFET driver
capable of controlling MOSFETs connected in a 3-phase
bridge arrangement and is specifically designed for automotive
applications with high-power inductive loads, such as BLDC
motors.
A unique charge pump regulator provides the supply for
the MOSFET gate drive for battery voltages down to 5.5 V
and allows the AMT49107 to operate with a reduced gate
drive down to 4.5 V. Gate drive strength is programmable
to help reduce EMC issues. A bootstrap capacitor is used
to provide the above-battery supply voltage required for
N-channel MOSFETs with a VCP charge pump facilitating
high side gate drive switching at any PWM duty cycle up to
and including 100.
Full control is provided over all six power MOSFETs in the
3-phase bridge, allowing motors to be driven with block
commutation or sinusoidal excitation. The power MOSFETs
are protected from shoot-through by integrated crossover
control and optional programmable dead time.
Integrated diagnostics provide indication of multiple internal
faults, system faults, and power bridge faults, and can be
configured to protect the power MOSFETs under most shortcircuit
conditions. For safety-critical systems, the integrated
diagnostic operation can be verified under control of the serial
interface.
The serial interface is provided to alter programmable settings
and read back detailed diagnostic information.
The AMT49107 is supplied in a 48-pin wettable flank QFN
package (suffix EV) with exposed thermal pad. The package
is lead (Pb) free with 100 matte-tin leadframe plating.
