Application Information
1. Mute Function
1) Mute Control Voltage Condition
When using the mute function, the applied control voltage condition is as follows.
2) Individual channel Mute Function
These pins are used for individual channel mute operation.
- When the mute pins (pin 37, 38 and 39) are OPEN or the voltages at the mute pins are below 0.5[V], the mute circuit is
disabled and BTL output circuits operate normally.
- When the mute pins (pin 37, 38 and 39) are above 2.5[V], the mute circuits are activated so that the BTL output circuit
will be muted.
- If the junction temperature rises above 175
°
C, then the thermal shutdown (TSD) circuit is activated and all the output
circuits (4-CH BTL Drivers and 3-phase BLDC Driver) are muted.
2. 4-CH Balanced Transformerless (Btl) Driver
- The voltage, Vbias, is the reference voltage given by the external bias voltage of pin 41.
- The input signals, Vin, through the pins (pin 22, 23, 24 and 25) are amplified 10K/Rextern times and then fed to the level
shift.
- The level shift produces the current due to the difference between the input signal (Vin) and the arbitrary reference
voltage (Vbias). The current produced as +
I and -
I are fed into the drive buffers.
- The drive buffer operates the power TR of the output stage according to the state of the input signal(Vin).
- The output stage is the BTL driver, and the motor (or actuator) rotates in forward direction, when TR Q1 and TR Q4 are
on. On the other hand, if TR Q2 and TR Q3 are on, the motor (or actuator) rotates in reverse direction.
- When the input signal Vin, through the pin (pin 22, 23, 24 and 25) is below the Vbias, then the motor (actuator) moves in
forward direction.
