VCC Power Supply Section
The VCC power supply delivers a voltage to the output circuit, charge pump circuit, and internal 5 V
circuit.
The operating voltage range is shown below:
VCC (opr.) = 10 to 27 V
This IC has a power monitoring function for preventing an output malfunction on power-up. However,
Toshiba recommends that IN1, IN2, and SB be set to the Low level at power-on.
7.
GND Sections
This IC includes two separate GND sections: S-GND for controlling and P-GND for outputting. Be sure
to short-circuit these two GNDs as close to TB6549 as possible.
8.
Power Monitoring Circuit
This circuit turns the output OFF when Vreg becomes 3.0 V (design target value) or less. At this time,
VCC = 4.6 V (typ.).
With a hysteresis of 0.3 V (design target value), the output turns back ON when Vreg exceeds 3.3 V
(design target value) after this circuit starts operating.
9.
Thermal Shutdown (TSD) Circuit
This IC includes a thermal shutdown circuit, which turns the output OFF when the junction temperature
(Tj) exceeds 160°C (typ.). The output turns back ON automatically. The thermal hysteresis is 20°C.
TSD = 160°C (design target value)
TSD = 20°C (design target value)
10. Overcurrent Detection (ISD) Circuit
This IC includes a circuit to detect current flowing through the output power transistors. The current limit
is set to 5 A (typ.). The circuit detects a current flowing through each of the four output power transistors.
If the current in any one output power transistor exceeds the set limit, this circuit turns all the outputs
OFF.
This circuit includes a timer that causes the outputs to be OFF for 50
s (typ.) after detection of an
overcurrent and then turn back ON automatically. If the overcurrent continues to flow, this ON-OFF
operation is repeated. Note that to prevent a malfunction due to a glitch, an insensitive period of 10
s
(typ.) is provided.
The set limit is 5 A (typ.) as a design target value. The distributions shown below exist because of the
variations in thermal characteristics of different ICs. These distributions should be fully considered in the
motor torque design.
Also, output peak current should be less than 3 A because of the variations below,
Detected current: Approximately from 3.5 to 6.5 A
