FM116C Description:
    The FM116C is an integrated circuit designed to drive small current DC motors in a SOT23-6 miniature package, ideal for space-sensitive system designs.
    The circuit adopts H-bridge structure and built-in power MOSFET switch, which can control the forward rotation, reverse, braking and standby of the load DC motor. The braking function can make the load motor stop rotating quickly, and the standby function makes the static power consumption of the circuit very low (less than 1uA).
    The circuit has a built-in low-resistance power MOSFET switch. Under the condition of 300mA load current, the circuit generates a voltage drop of 500mV and a power consumption of 150mW. Within the range allowed by the SOT23-6 package, the circuit can work continuously for a long time.
    The FM116C has built-in thermal protection (TSD) with hysteresis effect. The maximum continuous output current of FM116C is 600mA at 27℃ and VDD=4V. Affected by the heat dissipation capacity of the package As the ambient temperature increases, the maximum continuous output current must be appropriately reduced.
    FM116C is available in SOT23-6 package.
