Constant-current calculation : IOUT = 0.1 ÷ RF Example : When an IOUT of 100mA is required, RF must be 1Ω.
Usage Notes
The constant current is set by the resource RF connected between RFG and ground according to the formula shown
above.

Note : The "-" input unstable state. When off, a high-impedance state.
• The ENA goes to the standby state with a low-level input, and to the operating state with a high-level input.
• The control input switches the forward/reverse mode.
