How to Meet 24V Hot Plug-In Test for Charge Front-End bq243xx
PDF, 112 Kb, 档案已发布: Jan 2, 2008
The maximum input voltage rating of the bq243xx family of ICs is 30 V. However, some customers like to perform a 24-V hot plug-in transient test to prove its high-voltage capability and reliability from a system level. It is important for system designers to properly design the charging system with correct system-level protections. Usually, a TVS (transient voltage suppression) Zener diode is used

The maximum input voltage rating of the bq243xx family is 30 V. However, some customers like to do high-voltage pulse transient tests to prove its high-voltage capability and reliability from a system level. This pulse transient voltage could be as high as 45 V with 1-A output current limit and 200-Вµs pulse width. It is important for system designers to properly design the charging system wi
