The industry's first gate drive optocoupler with integrated flyback controller brings a highly compact and energy-efficient 6-channel IGBT driver module
[October 17, 2013] Avago Technologies (Nasdaq: AVGO), a leading supplier of analog interface components for wired, wireless and industrial applications, today announced the launch of a new 2.5A smart door drive optocoupler ACPL-32JT for automobiles, It can bring about power isolation in automotive power systems. This product integrates a flyback controller to support regulated output, as well as complete anti-failure IGBT diagnosis, protection and fault return functions that can meet the requirements of automotive safety functions. ACPL-32JT is very suitable for electric vehicle (EV, Electric Vehicle), hybrid electric vehicle (HEV) and plug-in vehicles such as automobile power system traction inverter, power converter, battery charger, air conditioner and oil pump motor drive Plug-in Hybrid Electric Vehicle (PHEV) application.
ACPL-32JT expands Avago's automotive R2Coupler series products. The main goal is to further simplify the design of automotive multi-channel IGBT drive circuit board. By integrating the flyback controller, ACPL-32JT can use fewer discrete components and match the volume. Small high-efficiency transformer, thus reducing the overall footprint and minimizing electromagnetic interference (ElectromagneTIc Interference, EMI) and noise coupling between IGBT channels, ACPL-32JT can help automotive power module design engineers develop a highly compact and energy-efficient 6-channel IGBT module.
At present, more than 50 EV, HEV, PHEV manufacturers and suppliers have adopted or are importing Avago's automotive R2Coupler products. Applications include battery management systems, power traction inverters, converters, chargers, air-conditioning compressors, Heater, oil pump, CAN bus interface, simulated environment sensing and fault feedback system, etc.

· Integrated flyback controller supports high voltage side power isolation
IGBT fail-safe protection: desaturation detection, IGBT soft turn-off, fault feedback, undervoltage lockout (UVLO) with feedback and active Miller clamp
· 8V to 18V wide input voltage range
· 2.5A maximum peak output current
· Vcm = 1, minimum 50 kV / μs common mode rejection (CMR) capability at 500V
· Simplify SO-16 package and minimize printed circuit board space and cost
Wide operating temperature range from -40 ° C to + 125 ° C
· Safety certification: UL1577, CSA and IEC / EN / DIN EN 60747-5-5 (please note that these important safety standards are not related to non-optical isolators such as magnetic isolators and capacitive isolators)
Avago will exhibit ACPL-32JT at the 2013 VDI International Conference held in Germany from October 16th to 17th.
Cheng-Dee Lee, Business Development Director of Avago's Isolation Products Division, said: "With the requirements of government regulations and energy-saving trends, the market for EV, HEV and PHEV automotive products will continue to grow. Avago's new ACPL-32JT will bring The isolated power supply compact smart door drive customers provide an effective solution to meet the strict size and safety requirements of automotive power systems. "

Avago's ACPL-32JT smart door drive optocoupler is currently available. For samples and output, please contact Avago direct sales channels or global distribution partners.
Dual-band WiFi module refers to the WiFi module that supports both 2.4GHZ and 5GHz bands. The dual-band WiFi module can operate in the 5Ghz band, which is much cleaner and can easily avoid interfering with each other. The advantage of 2.4G is that it has good ability to penetrate the wall, and the disadvantage is that it is easy to be disturbed. The advantages of 5G are strong anti-interference ability, wide band width, high throughput rate, and strong scalability, but the disadvantage is that 5G is only suitable for indoor small-range coverage and outdoor bridge, and the attenuation effect of various obstacles on it is much larger than 2.4g.
Dual-band WiFi module has a stronger and more stable Wifi wireless signal, higher transmission speed, and can make wireless devices more power-saving, to meet the future high-definition and big data wireless transmission needs.
When selecting a dual-frequency WiFi module, we should pay attention to these parameters of the WiFi module: size, package, frequency range, data rate, transmission rate, transmission distance, communication interface, power supply voltage, antenna interface, etc.
Dual frequency WiFi module can well meet the functional needs of users, increase the competitiveness of the product, while the WiFi module is easy to use, can shorten the user product development cycle, speed up the product market! Users can make choices according to actual needs!
Choosing a dual-band WiFi module may need to pay attention to the following points:
(1) Consider the transmission power of the dual-frequency WiFi module
The transmitting power of the WIFI module is generally about 18dBm, and the transmitting power of the high-power WIFI module is about 28dBm.
(2) Transmission rate
Consider whether the dual-band WiFi module supports MIMO technology (that is, allows multiple antennas to send and receive multiple spatial streams simultaneously)
(3) Consider the application interface that dual-band WiFi modules can provide, which is also very important.
(4) According to the requirements of the application scenario to choose the dual-band WiFi module, not the higher the configuration, the better, the application is good, excess waste!
