From November 23 to 27, 2023, the 2nd Global Digital Trade Expo was held in Hangzhou International Expo Center. For the first time, the exhibition set up a national patent-intensive products exhibition area with the theme of "Digital Leads Product Innovation and Patents Promote Industrial Development", focusing on high-value patented products with cutting-edge technology in the national industry. As the representative of "Little Giants" enterprises, JoulWatt brought several innovative patented products to the exhibition area.

Patented Products - JWQ7924

The JWQ7924 is a dual-channel high-speed low-side gate driver capable of efficiently driving MOSFET and IGBT power switches with rail-to-rail drive capability and very low propagation delays, and can input up to 4.5A pull current and 4.5A sink current into capacitive loading.

Product Features

AEC-Q100 G1 qualified

Two independent gate-drive channels

4.5A peak source and sink-drive current

Fast propagation delays (13ns typical)

0.5ns typical delay matching between two channels

Patented Products - JW3376

The JW3376 is a high-performance and reliable analog front-end (AFE) device for 11~16 series Li-ion, Li-polymer, and Li-FePO4 battery packs. Through SPI communication, JW3376 can be used by host controllers to perform several battery pack management functions, such as monitoring (battery voltage, battery current, battery temperature), protection (controlling charge/discharge FETs), and equalization. The integrated analog-to-digital (A/D) converter enables purely digital readout of key system parameters.

Product Features

- Self-developed, high-voltage and low-voltage compatible process

- High precision ΔΣ ADC

- Low power consumption for extended standby time

- Comprehensive protection, reducing the number of peripheral components
