Application Informations

1. Logic Inputs and Outputs

FAN8010MP has two input pins, IN1and IN2. The following truth table shows the relationship of the inputs and out-

puts.

2. Constant Output Current Control

The voltage, V pin is 0.2V typically which is obtained by a internal reference and a resistor divider as shown in

ADJ

the figure. The V

is used as the output current command and can be adjusted by the external resistor R

OPT

ADJ

between ADJ and GND. The output current is converted to the voltage V through the current sense resistor R

By the negative feedback loop, the V is regulated to V

. Actually 50mW, which is the sum of the internal bond-

ADJ

ing resistance and internal metal resistance, should be added to the R The output current is calculated

as followings ;

I_O= (V_ADJ) ⁄ (R_S+ R_W)= 1.38(R_OPT7K) ⁄ {(40K + R_OPT7K)(R_S+ R_W)}

IN1~2

Sense

If oscillation or overshoot get loaded on the output current, they can be removed by connecting a ceramic capacitor

ranged from 1nF to 10nF between the FC pin and GND. When a capacitor is used, output response time is delayed

as the capacitance increases.

3. Unregulated Voltage Control

When the exact current control is not needed, the sense pin should be connected to the GND, and FAN8010MP is

operated as a normal H-bridge driver.

4. Thermal Shutdown

Thermal Shutdown Circuit turns OFF all outputs when the junction temperature typically reaches 175°C. It is

intended to protect the device from failures due to excessive junction temperature.

The Thermal Shutdown has the hysteresis of 25°C approximately.
