Shenzhen Mingjiada Electronics Co., Ltd New and Original [BOSCH Bosch] CR636A / CR636 14V Alternator Voltage Regulator, Setting Voltage 11.0 - 15.5 V, Multiwatt8 Package or Bare Chip.


Technical Summary

The CR636A / CR636 regulates the output voltage of a 14V alternator to a constant value.


The regulator continuously senses the alternator output voltage, speed, temperature, and excitation current. It regulates the excitation current to keep the output voltage constant. The output voltage can be adjusted to any value within the established range by means of a PWM command.


Technical features

Stability of operation

Wake-up from V terminal if communication is lost

Protection of alternator and battery

Switching off of power tubes at extreme temperatures

Short circuit protection/recovery of DF power tubes

High-side DMOS regulation of the generator field (DF) via fixed-frequency PWM

Ultra-high-speed continuous-current MOSFETs integrated on the DF

DF duty cycle range up to 90 %

LR low speed loading

LR Boost and fast loading

Active handling of overvoltage

Accepts 28V jump start

Communication features
