VCC Power Supply
VCC supplies a voltage to the output circuit and the internal 5-V circuit.
The operating voltage range is:
VCC (opr.) = 10 to 30 V
IN1, IN2, and SB should be set Low at power-on. (In direct PWM mode, OSC/PWM should also be set
Low.)
GND Section
The TB6559FG has two separate grounds: S-GND for the control circuitry and P-GND for the output
circuitry. S-GND and P-GND should be short-circuited at a location as close to the TB6559FG as possible.
ALERT Circuit
When either the thermal shutdown or overcurrent protection circuit is activated, the ALERT output goes
High (CMOS output). When the ALERT pin is changed from low to high or vice versa, its output signal
may become unstable, causing chattering or noise pulses. To avoid such instability, it is recommended to
insert an RC filter to the output line.
Normal operation: Low
Protective operation: High
Thermal Shutdown (TSD) Circuit
The TB6559FG incorporates a thermal shutdown circuit. When the junction temperature (Tj) exceeds
160°C (typ.), the output transistors are turned off.
The output transistors are automatically turned on when the junction temperature cools past the shutdown
threshold, which is lowered by a hysteresis of 40
°C.
The IC has 40°C of temperature hysteresis.
