Secondary programmable power chip
This analog-digital hybrid programmable power management IC integrates a precision 2.5V reference, configurable error amplifiers, 8-channel 10-bit ADC, I²C controller, digital control module, and LED constant-current drivers. Featuring ultra-low power consumption and high flexibility, it enables advanced power systems when paired with a low-cost 8-pin MCU (no ADC required), making it ideal for intelligent battery management applications.
Precision adjustable voltage regulator
A three-terminal adjustable voltage regulator with excellent thermal stability across operating temperatures. Output voltage (2.5V-36V) is set by external divider resistors. With 0.2Ω dynamic impedance and fast transient response, it can replace Zener diodes in applications.
Battery charging management chip
This AC/DC lead-acid battery charger IC features automatic CC/CV/float stage transition and integrated dual-LED driver, minimizing external components while enhancing reliability. Its three precision voltage references (for each charging phase) and resistor-configurable parameters support diverse battery requirements.
Battery charging management chip
Designed for AC/DC lithium battery charging, this IC automates CC/CV/indicator transitions with built-in dual-LED driver. It integrates 2.5V/140mV/20mV references, two op-amps, a current comparator, and LED driver. External resistors configure output parameters for Li-ion charging management.
Charger timing chip
A charger-specific timer IC with total/current timing counters for EV/battery chargers. Operating at +3V to +5.5V, this CMOS-based 8-pin device reduces component count, cost, and PCB space.
