SLM823xProduct Introduction
Following the successful release of SLM34x in July, Siming Semiconductor has recently launched a dual channel isolated drive SLM823x,The maximum driving current of the SLM823x series products ranges from 1.0A to 4.0A, and there are two options for undervoltage lockout (UVLO), 8.5V/7.5V and 12.5V/11.5V. By adopting industry-leading dual capacitor isolation technology and "OOK" transmission technology, an isolation voltage of 5kVrms and an isolation surge voltage of up to 10kV have been achieved, with a common mode transient immunity (CMTI) of over 100kV/us, ensuring reliable and stable operation in extremely harsh working environments. It can be widely used in server/telecommunications/industrial AC/DC, DC/DC power modules, uninterruptible power supply (UPS), EV charging, motor drive and other fields. The packaging of SLM823x is SOIC16 wide body as shown in Figure 1, providing a creepage and clearance distance greater than 8mm.
SLM8233 Typical Application Circuit
The typical application circuit diagram of SLM8233 is shown in Figure 2. The chip has Overlapping protection, programmable dead time setting, and supports a wide range of input voltage from 3V to 18V and an output voltage of up to 40V.
Performance Comparison of SLM823x
Compared with the dual channel isolation drive of mainstream international manufacturers in the market, SLM823x has the advantages of wider voltage range, stronger negative pressure resistance, and superior anti-interference ability.
