Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | R/C | passive | External R-C timing network input that sets the on-chip oscillator frequency (f = 1/(0.69·R·C) for R>10kΩ). |
| 2 | OSC. | passive | Oscillator node with internal discharge resistor of 1kΩ ±30% switching between the lower (0.33·VCC) and upper (0.66·VCC) thresholds; sets oscillator frequency range 5 to 70kHz. |
| 3 | SYNC | bidirectional | Synchronization pin; connecting the sync pins of multiple L6506 devices to the master's oscillator output allows the master to set the operating frequency of all chips. |
| 4 | POWER ENABLE | input | TTL-compatible logic input (VIH ≥2V, VIL ≤0.8V) that enables the four output drivers. |
| 5 | IN 1 | input | TTL-compatible logic input (VIH ≥2V, VIL ≤0.8V) controlling output channel 1 (OUT1) through the internal AND gate/flip-flop. |
| 6 | IN 2 | input | TTL-compatible logic input (VIH ≥2V, VIL ≤0.8V) controlling output channel 2 (OUT2) through the internal AND gate/flip-flop. |
| 7 | IN 3 | input | TTL-compatible logic input (VIH ≥2V, VIL ≤0.8V) controlling output channel 3 (OUT3) through the internal AND gate/flip-flop. |
| 8 | IN 4 | input | TTL-compatible logic input (VIH ≥2V, VIL ≤0.8V) controlling output channel 4 (OUT4) through the internal AND gate/flip-flop. |
| 9 | GND | power_in | Ground reference pin for the device. |
| 10 | N.C. | unconnected | Not internally connected pin (package pin present on SO20 but unused by the die). |
| 11 | N.C. | unconnected | Not internally connected pin (package pin present on SO20 but unused by the die). |
| 12 | VSENSE 1 | input | Comparator input sensing the voltage across the external current-sense resistor for channel 1, input voltage range -0.3V to 3V, compared against REF1 to regulate peak current. |
| 13 | OUT 4 | output | TTL-compatible logic output for channel 4 (VOH 2 to 3.5V at IOH=400µA, VOL 0.25 to 0.4V at IOL=4mA, source current 2.75mA typ.) driving the external power stage. |
| 14 | OUT 3 | output | TTL-compatible logic output for channel 3 (VOH 2 to 3.5V at IOH=400µA, VOL 0.25 to 0.4V at IOL=4mA, source current 2.75mA typ.) driving the external power stage. |
| 15 | OUT 2 | output | TTL-compatible logic output for channel 2 (VOH 2 to 3.5V at IOH=400µA, VOL 0.25 to 0.4V at IOL=4mA, source current 2.75mA typ.) driving the external power stage. |
| 16 | OUT 1 | output | TTL-compatible logic output for channel 1 (VOH 2 to 3.5V at IOH=400µA, VOL 0.25 to 0.4V at IOL=4mA, source current 2.75mA typ.) driving the external power stage. |
| 17 | VSENSE 2 | input | Comparator input sensing the voltage across the external current-sense resistor for channel 2, input voltage range -0.3V to 3V, compared against REF2 to regulate peak current. |
| 18 | REF 1 | input | Reference voltage input setting the peak-current threshold (Vref) for the channel-1 comparator; Ipeak = Vref/Rsense. |
| 19 | REF 2 | input | Reference voltage input setting the peak-current threshold (Vref) for the channel-2 comparator; Ipeak = Vref/Rsense. |
| 20 | VCC | power_in | Positive supply voltage pin, operating range 4.5V to 7V, absolute maximum 10V, quiescent supply current up to 25mA at VCC=7V. |
