RESET — A logic input used to enable the device, internally
pulled up to V LCAP (+5 V). A RESET = 1 will disable the device
and force all gate drivers to 0 V, coasting the motor. A RESET
= 0 allows the gate drive to follow the commutation logic. The
RESET = 1 overrides BRAKE.
GLA/GLB/GLC — Low-side, gate-drive outputs for external
NMOS drivers. External series-gate resistors (as close as pos-
sible to the NMOS gate) can be used to control the slew rate
seen at the power-driver gate, thereby controlling the di/dt and
dv/dt of the SA/SB/SC outputs. GLx = 1 (or “high”) means that
the upper half (PMOS) of the driver is turned on and its drain
will source current to the gate of the low-side FET in the exter-
nal motor-driving bridge. GLx = 0 (or “low”) means that the
lower half (NMOS) of the driver is turned on and its drain will
sink current from the external FET’s gate circuit.
SA/SB/SC — Directly connected to the motor, these terminals
sense the voltages switched across the load. These terminals are
also connected to the negative side of the bootstrap capacitors
and are the negative supply connections for the ? oating high-
side drivers.
GHA/GHB/GHC — High-side, gate-drive outputs for external
NMOS drivers. External series-gate resistors can be used to
control the slew rate seen at the power-driver gate, thereby con-
trolling the di/dt and dv/dt of the SA/SB/SC outputs.
GHx = 1 (or “high”) means that the upper half (PMOS) of the
driver is turned on and its drain will source current to the gate of
the high-side FET in the external motor-driving bridge. GHx =
0 (or “low”) means that the lower half (NMOS) of the driver is
turned on and its drain will sink current from the external FET’s
gate circuit.
CA/CB/CC — High-side connections for the bootstrap capaci-
tors, positive supply for high-side gate drivers. The bootstrap
capacitors are charged to approximately V REG when the asso-
ciated output Sx terminal is low. When the output swings high,
the voltage on this terminal rises with the output to provide the
boosted gate voltage needed for N-channel power MOSFETs.
