Technical Note

●Function Explanation

1) Power-saving function (all series)

When the L voltage is applied the PS pin, the IC’s inside circuit stop, and when 0V applied, the circuit current became

0μA(Typ.), especially.

When the IC drive, serial input while the PS pin applied H voltage. (See the electrical characteristics; P.3, 4, 5/16)

2) Control Input Pin

（Ⅰ）IN pin (BD6883GUL, BH6453GUL)

The IN pin is used to program and control the motor drive modes.

(See the electrical characteristics; P3, 4/16, and the I/O Truth Table; P12/16)

（Ⅱ）INA, INB, SEL pins (BD6886GUL, BD6369GUL)

The INA and INB are used to program and control the motor drive modes.

When the L voltage is applied to the SEL pin, the I/O logic can be set to EN (Enable)/IN mode, and when the H voltage is applied

to the one, the I/O logic can be set to IN/IN mode. (See the electrical characteristics; P5/16, and the I/O Truth Table; P12/16)

3) H-bridge and Half-bridge on the output stage (ALL series)

Specify maximum current applied to the H-bridge and Half-bridge within the operating range, in consideration of power dissipation.

(See the Operating Conditions; P.2/16)

4) Drive system of Linear Constant-Voltage H-bridge (BD6883GUL, BD6886GUL, and BD6369GUL)

To set up the output H voltage, when the voltage input to the VLIM pin, the output H voltage is two times as high as the voltage.

（Ⅰ）BD6883GUL

The output H voltage VOH [V] = 2.0×VLIM [V]

(When VLIM [V] ＞

VCC [V] , Output H voltage is about VCC voltage)

･････①

（Ⅱ）BD6886GUL, BD6369GUL

The output H voltage VOH [V] = 2.0×VLIM [V] (When VLIM [V] ＞ VM [V] , Output H voltage is about VM voltage)

･････②

For example, the output voltage is 2.0V±5%, if 1.0V is applied to the VLIM pin.

If the VLIM pin is shorted to the VM pin (or the same voltage level as the VM is applied), you can be used as a Full-ON Drive

H-bridge.

5) Drive system of Linear Constant-Current H-bridge (BH6453GUL)

To detect the output current and the output current settings

The BH6453GUL built in resistor for output current detect. The output current is kept constant by comparing it with the CLIM

voltage. In addition, impress a highly accurate voltage form the outside of IC to the CLIM terminal, when you do the output current

setting accuracy or more good.

Output current ISINK [A] = CLIM [V]

2×2(Typ) [Ω]

･････③

If the CLIM pin applied 0.8V, Output current is 200mA±10%.
