The YP6170 is an ASIC chip intended for small‑power solar LED lawn lighting. It integrates a switch‑type driver, light‑control circuit, battery over‑discharge protection and LED shut‑down circuit, allowing a complete lighting solution with only a few external components.
Key features include a wide operating voltage range (0.8‑6 V), adjustable LED current (10‑160 mA), low shut‑down current (<30 µA), high efficiency (>86 %), and configurable light‑control sensitivity using either a solar panel or a photo‑resistor. The chip also provides over‑discharge protection with a programmable threshold and supports driving 1‑8 LEDs. This manual is written in Chinese.
| VDD input voltage | 0.8‑6 V |
|---|---|
| LED current | 10‑160 mA |
| Operating temperature range | -40~+125 ℃ |
| Maximum voltage (VMAX) | 8 V |
| Maximum LX current (LMAX) | 0.8 A |
| Light‑control comparator threshold (Vsld_th) | 190‑210 mV |
| Over‑discharge comparator threshold (Vuv_th) | 475‑525 mV |
| Oscillator frequency (Fosc) | 100‑1000 kHz |
The chip operates with a VDD input voltage from 0.8 V to 6 V.
Brightness is adjusted by changing the inductance L value, which changes the current supplied to the LED.
A comparator with a threshold around 500 mV and a hysteresis of 100 mV provides over‑discharge protection.
The chip can operate from –40 °C up to +125 °C.
