Application Information
1. BAKE AND MUTE FUNCTION
Of the four channel drivers, channel 1 has a brake function, and the other channels have a mute function.
When the BRAKE (pin23) is set to high level, both channel 1 outputs go low level. (Brake mode).
When the MUTE2 (pin21) is set to high level, the channel 2 output is muted.
When the MUTE34 (pin19) is set to high level, the channel 3 and 4 outputs are muted.
2. REFERENCE VOLTAGE(VREF) DROP MUTE
When the voltage applied to VREF (pin16) is 1.0V or less (typical), the H-bridge driver outputs are set to high impedance.
3. THERMAL SHUTDOWN (TSD)
If the chip temperature reaches 150
°
C (typical), the H-bridge driver output current is cut-off and the thermal shut down
circuit has a hysteresis temperature of 25
°
C.
4. H-BRIDGE DRIVER (4-CHANNELS)
The driver input resistance is 11K
(typical) for channels 1, 3 , and 4, and 7.5K
for channel 2. Set the gain according to
the following formula.

is externally connected input resistance.
5. SWITCHING REGULATED POWER SUPPLY DRIVE
The power supply of H-bridge driver consists of DVCC(pin36) for output stage power supply and VSYS2 (pin15) for
predriver power supply.
