2. Constant Output Current Control
The voltage, VADJ pin is 0.2V typically which is obtained by a internal reference and a resistor divider as shown in the figure. The VADJ is used as the output current command and can be adjusted by the external resistor ROPT between ADJ and GND. The output current is converted to the voltage VS through the current sense resistor RS. By the negative feedback loop, the VS is regulated to VADJ. Actually 50mW, which is the sum of the internal bonding resistance and internal metal resistance, should be added to the RS. The output current is calculated as followings ;
I O = ( V ADJ ) ( R S + R W ) = 1.38 ( R OPT || 7K ) { ( 40K + R OPT || 7K ) ( R S + R W )}

OUT1 M
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 175C. It is intended to protect the device from failures due to excessive junction temperature. The Thermal Shutdown has the hysteresis of 25C approximately.
