Alternator regulator Chips
MQ-1399AR
An integrated circuit intended to regulate the output voltage of a 14/28V automotive alternator. It allows keeping the battery at its nominal charge and delivering current to electrical devices within the vehicle.
To temporarily manage the important alternator output current variation and limit torque variation.

Instrument Amplifier
MQ-8426 & MQ-8228
Application:
- Industrial process controls
- Bridge amplifiers
- Medical instrumentation
- Portable data acquisition
- Multichannel systems
The MQ8426 is designed to make PCB routing easy and efficient. The two amplifiers are arranged in a logical way so that typical application circuits have short routes and few vias. It is ideal for multichannel, space-constrained industrial applications. Unlike other low cost, low power instrumentation amplifiers, it is designed with a minimum gain of 1 and can easily handle ±10 V signals. With its space-saving LFCSP package and 125°C temperature rating.
The MQ8228 is the single-channel version of the MQ8426.
