TB6556FG 2012-10-22 5 Pin Description Symbol Input/Output Signal Input/Output Internal Circuit Lead angle setting signal input pin 0 V: 0° 5 V: 58° (5-bit AD) LA When LA is fixed externally, connect LL to GND and UL to Vrefout, and then input the setting voltage to the LA pin. Input voltage range: 0 V to 5.0 V (Vrefout) Input voltage of Vrefout or higher is clipped to Vrefout. When LA is fixed automatically, open the LA pin. In this state, the LA pin is used only for confirmation of LA width. Gain setting signal input (LA setting) Gin Gout Non-inverted amplifier 25 dB (max) Gout output voltage LOW: GND HIGH: VCC − 1.7 V Peak hold (LA setting) PH Connect the peak-hold capacitor and discharge resistor to GND, parallel to each other. 100 k Ω/0.1μF recommended Low-pass filter (LA setting) LPF Connect the low-pass filter capacitor Built-in 100 k Ω (typ.) resistor 0.1 μF recommended Lower limit for LA LL Clip lower limit for LA LL = 0 V to 5.0 V When LL UL, LA is fixed at LL value.
