Slkor(SLKORMICRO Elec.) · Power Management Specialized - PMIC · SOP-14
SL2044 from Slkor(SLKORMICRO Elec.), in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OSC | passive | Oscillator pin of the RC timing network (R1, C1) that sets the flash frequency per formula 5.1, with R1 from 6.8kΩ to 180kΩ and C1 up to 47µF. |
| 2 | SIL | input | Left turn start input; grounding it (via pull-down R4) disables the left indicator, and closing the left switch changes the internal comparator state to drive outputs on pins 11 and 13. |
| 3 | SIR | input | Right turn start input; grounding it (via pull-down R5) disables the right indicator, and closing the right switch changes the internal comparator state to drive outputs on pins 11 and 13. |
| 4 | SIHW | input | Hazard warning start input, active low; when the hazard switch closes both turn indicators flash at the frequency set by formula 5.1, independent of the ignition state. |
| 5 | VS | power_in | Battery supply input that powers the fault-detection comparator on pin 8 and may be connected directly to the external battery; absolute maximum 24 V for 1 minute with pins 5, 9 and 12. |
| 6 | CR1 | input | Relay 1 feedback input that monitors the left indicator operating state and also enables the oscillator. |
| 7 | CR2 | input | Relay 2 feedback input that monitors the right indicator operating state and also enables the oscillator. |
| 8 | LD | input | Lamp fault detection input that senses indicator current across external shunt Rs against an internal 81 mV comparator reference, doubling the flash rate on a lamp failure. |
| 9 | VS | power_in | Supply pin for the oscillator, comparators and internal logic, rated 8 V to 18 V with 24 V absolute maximum for 1 minute. |
| 10 | GND | power_in | Reference ground pin, connected through resistor R2 to limit transient pulses, with built-in reverse battery polarity protection. |
| 11 | OR1 | output | Relay 1 driver output for the left indicator, with low saturation voltage (1.0 V at 8 V supply, 1.2 V at 12 V supply) and up to 300 mA relay current. |
| 12 | VS | power_in | Supply pin for the relay driver circuit, internally clamped by a 27 V zener diode (clamp voltage 25.0 V to 30.0 V). |
| 13 | OR2 | output | Relay 2 driver output for the right indicator, with low saturation voltage (1.0 V at 8 V supply, 1.2 V at 12 V supply) and up to 300 mA relay current. |
| 14 | OSC | passive | Second oscillator pin of the RC timing network (R1, C1) that sets the flash frequency per formula 5.1. |
