[Regulator Voltage Drop]

When the regulator voltage drops to 2.7V (typ.) or less, the reset output will become ‘L’ while the mute

function will turn ON and, when the voltage recovers to 2.9V (typ.) or above, the reset output will

become ‘H’ while the mute function will turn OFF.

[Bias Drop]

When the bias terminal (pin 23) voltage has dropped to 0.7V (typ.) or less, the mute function will turn

ON while the reset output will become ‘L’. Under conditions of normal use, it should be set to 1.2V or

above.

[Thermal Shutdown]

When the chip temperature has reached to 175°C (typ.) or above, the mute function will turn ON while

the reset output will become ‘L’. Ten the chip temperature has dropped to 150°C (typ.) or less, the

mute function will turn OFF while the reset output will become ‘H’.

[Mute]

When the mute terminal (pin 7) voltage has set to open or dropped to 0.5V (typ.) or less, the mute

function will turn ON while the reset output will not change.

About reset

terminal

Inserting a capacitor between the reset

terminal (pin 16) and GND can set the delay time for the

reset output.

The delay time t [sec] can be expressed by the following equation, where C[F] is a capacitance of

the capacitor to be connected;

t=CV/I

When V=1.14[V], I=23.7[µA ] (typ.) and the capacitor with the capacitance of 4.7

µF

is connected,

the delay time will become approximately 220msec.

Thermal shutdown (TSD), mute ON, bias terminal voltage drop, or regulator voltage drop will activate

the mute function, where only the driver part can be muted. While muting, the voltage at the output

terminal will equal to the internal bias voltage (approximately (VCC-VF) / 2).

The capacitor installed between the regulator output (pin 6) and GND also serves as an anti-oscillation

capacitor and therefore, it is required to have high performance in the temperature characteristics.

While the regulator is not in use, the regulator output terminal (pin 6) must be shorted to VCC and the

regulator external Tr base connection terminal (pin 5) must be open.

The radiating FIN must be connected to the external GND.

Short-circuits between output pin-VCC, output pin-GND, or output terminals (load short) must be

avoided. Make sure that the ICs are installed on the board in proper directions.

Mounting the ICs in improper directions may damage them or produce smoke.

About absolute maximum ratings

Exceeding the absolute maximum ratings, such as the applied voltage or the operating temperature

range, may cause permanent device damage. As these cases cannot be limited to the broken short

mode or the open mode, if a special mode where the absolute maximum ratings may be exceeded is

assumed, it is recommended to take mechanical safety measures such as attaching fuses.

About power supply lines

As a measure against the back current regenerated by a counter electromotive force of the motor, a

capacitor to be used as a regenerated-current path can be installed between the power supply and

GND and its capacitance value should be determined after careful check that any problems, for

example, a leak capacitance of the electrolytic capacitor at low temperature, are not found in various

characteristics.

About GND potential

The electric potential of the GND terminal must be kept lowest in the circuitry at any operation states.

About thermal design

With consideration of the power dissipation (Pd) under conditions of actual use, a thermal design

provided with an enough margin should be done.

(12) About operations in a strong electric field

When used in a strong electric field, note that a malfunction may occur.

(13) ASO

When using this IC, the output Tr. must be set not to exceed the values specified in the absolute

maximum ratings and ASO.

(14) Thermal shutdown circuit

This IC incorporates a thermal shutdown circuit (TSD circuit). When the chip temperature reaches the

value shown below, the coil output to the motor will be set to open.

The thermal shutdown circuit is designed only to shut off the IC from a thermal runaway and not

intended to protect or guarantee the entire IC functions.

Therefore, users cannot assume that the TSD circuit once activated can be used continuously in the

subsequent operations.

(15) About earth wiring patterns

When a small signal GND and a large current GND are provided, it is recommended that the large

current GND pattern and the small signal GND pattern should be separated and grounded at a single

point of the reference point of the set in order to prevent the voltage of the small signal GND from being

affected by a voltage change caused by the resistance of the pattern wiring and the large current.

Make sure that the GND wiring patterns of the external components will not change, too.

(16) This IC is a monolithic IC which has a P

isolations and P substrate to isolate elements each other.

This P layer and an N layer in each element form a PN junction to construct various parasitic elements.

Due to the IC structure, the parasitic elements are inevitably created by the potential relationship.

Activation of the parasitic elements can cause interference between circuits and may result in a

malfunction or, consequently, a fatal damage. Therefore, make sure that the IC must not be used

under conditions that may activate the parasitic elements, for example, applying the lower voltage than

the ground level (GND, P substrate) to the input terminals.

Note that, while not applying the power supply voltage to the IC, any voltage must not be applied to the

input terminals. In addition, do not applying the voltage to input terminals without applying the power

supply voltage to the IC. Also while applying the power supply voltage, each input terminal must be

the power supply voltage or less; or within the guaranteed values in the electric characteristics.
