Description

Aug 25, 2008 IRS21850S . SINGLE HIGH SIDE DRIVER IC. IC Features. Gate drive supply range from 10 V to 20 V. Undervoltage lockout for VBS and VCC. Gate voltage must be 10 V to 15 V higher than the source voltage. Being a high- side switch, such gate voltage would have to be higher than the rail voltage, For robust and safe operation, designers of ac-dc and isolated dc-dc switch mode pow- er supplies (SMPS), uninterruptible power supplies (UPS), solar inverters There are four single channel devices which incorporate current sensing. The IR2121 and. IR2125 are low and high side drivers respectively, which have a high Nov 10, 2008 ON Semiconductor and the ON Semiconductor logo are trademarks of Semiconductor Components Industries, LLC dba ON Semiconductor or
