The FL5150 and FL5160 are controllers for varying the pulse width for AC loads. The FL5150 is for 50 Hz and the FL5160 is for 60 Hz applications. The FL5150/60 is powered from the AC line and generates a programmable gate drive for controlling the pulse width for external IGBT or MOSFET transistors. The pulse width can be user programmable with either an external resistor or 0 to 10 V DC signal or controlled by a µP with a logic signal. The pulse width can be controlled from 0 to 100% duty cycle to provide a wide AC symmetric dimming control function when biased with a 3-wire application. For 2-wire Line-Hot and Load-Hot applications, the pulse width can typically be varied from 0 to a maximum gate pulse so that the load voltage is >95% of the AC line voltage. The FL5150/60 will automatically override the pulse width control setting to allow maximum gate pulse width without flicker.The FL5150/60 takes advantage of the UL1472 2015 2nd edition code revision that allows for up to 0.5 mA of ground leakage current when a neutal wire is not available in the switch box. This improves the ficker performance for non-resistive loads. If the application does not allow ground leakage current then the Line Hot signal can be used as the ZC signal.
The FL5150/60 has user programmable over-current and temperature protection. With external sense resistors, the maximum voltage drop across Q1 and Q2 can be set to limit the maximum current and transistor power dissipation.
The FL5150/60 can be programmed for trailing edge dimming when the DIM Mode pin is low at startup (pulse width starts at the zero-crossing) or leadig edge dimming when the DIM Mode pin is connected to the VDD pin at startup (pulse width ends at the zero crossing). When an OFF state is selected (DIM Control pin is 0 V) the FL5150/60 will go into a low power electronic OFF state that reduces the power consumption to less than 100mW if an external NPN transistor is used.
The FL5150/60 has an internal 8 bit ADC that allows for typically 226 selectable dimming pulse widths with a resolution of 25 µs per step. The FL5150/60 controls the dim pulse width rate of change so that the minimum to maximum dim ramp time is approximately 1 second. This feature allows for a smooth dim transition.Internally, the FL5150/60 contains a 17 V shunt regulator, 5 V linear regulator, 8Bit ADC, detection comparators, control logic and an IGBT or MOSFET gate driver.
The 10-pin SOIC package provides for a low-cost, compact design and layout.
