Key Features:
繁體中文版
This series is dedicated to the type of vehicle Trio 14 / 28V alternator voltage regulator
designed chip.
Low-side alternator can be used to provide single or dual voltage detection voltage
feedback control, the output PWM signal drives N-channel MOSFET, to control the
excitation current changes alternator.
It can keep the battery in the normal charge and provides current to the electrical
equipment within the vehicle. Provide field short protection.
- Capable of regulating voltage within ±0.2 V @ 25°C
- Load Dump protection
- Field short protection
- < 0.5 mA standby current from battery @ 25°C
* UL8805 : in qualification
This series combines high performance at low cost. This series of products for the car
14 / 28V alternator regulator designed chip.
It can be used in low-end or high-end alternator, offers single or dual voltage detection
voltage feedback control,provide an external N channel MOSFET control, output PWM
