TB67B000HG
TOSHIBA Bi-CMOS Power Integrated Circuit Multi-Chip Package (MCP)
TB67B000HG
High voltage
3-Phase Full-Wave Sine-Wave PWM Brushless Motor Driver
The TB67B000HG is a high-voltage PWM BLDC motor driver.
The product integrates a sine-wave PWM/wide-angle
commutation controller and the high-voltage driver in a single
package (“two-in-one”). It is designed to change the speed of a
BLDC directly motor by using a speed control signal (analog)
from a microcontroller.

Functional Description
1. Basic operation
The motor is driven by 120° commutation. When the positional signal reaches number of rotations f = 1 Hz
or higher, the rotor position is estimated according to the positional signal and the motor is driven with the
lead angle based on the input voltage of the LA pin.
From start to 1 Hz: Driven by square wave (120° commutation)
1Hz or higher: Driven by sine-wave PWM (180° commutation) or wide-angle commutation (150°
commutation)
When fosc = 5MHz, approx. 1 Hz.
*: When f is 1Hz or higher, the motor is driven by the command of the LA pin.
When f is 1Hz or less or the motor is driven with reverse rotation direction (according to the timing
chart), it is driven by 120° commutation (lead angle is 0°).
Driven system (sine-wave PWM or wide-angle commutation) can be switched by the SS pin. Setting of lead
angle is different between these driving systems.

Voltage Command (VSP) Signal and Bootstrap Voltage Regulation
(1) When VSP ≤ 1.0 V:
The commutation signal outputs are disabled (i.e., gate protection is activated).
(2) When 1.0 V < VSP ≤ 2.1 V:
The low-side transistors are turned on at a regular (PWM carrier) frequency. (ON duty: 18/fosc)
(3) When 2.1 V < VSP ≤ 7.3 V:
During sine-wave PWM drive, the commutation signals directly appear externally. During
square-wave drive, the low-side transistors are forced on at a regular (PWM carrier) frequency. (ON
duty: 18/fosc)
In stop state (Forward: 1Hz or less, Reverse: 5Hz or less), commutation signals are outputted after
VSP (VSP > 2.1 V) is inputted and the refresh function operates for 1.5ms (typ.). In operation state
(Forward: more than 1Hz, Reverse: more than 5Hz), commutation signals are outputted after VSP
(VSP > 2.1 V) is inputted.
Note: In startup, low-side transistor should be turned on (1.0 V < VSP <= 2.1 V) for a certain period to charge gate
power supply of high-side transistors.
(4) When 8.2 V ≤ VSP ≤ 10 V (test mode for motor shipping):
The TB67B000HG drives in sine-wave drive mode with lead angle of zero. However, it drives in
square-wave mode in detecting reverse rotation.
When VSP reaches 7.9 V (typ.), lead angle switches to zero.
The PWM duty cycle is calculated as PWM_carrier_frequency × 92% (typ.) and kept the constant
value (5.4 V(typ.) ≤ VSP).
