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
S
S.
By the negative feedback loop, the V is regulated to V
. Actually 50mW, which is the sum of the internal bond-
S
ADJ
ing resistance and internal metal resistance, should be added to the R The output current is calculated

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.
