产品概述
描述
The OCVPB21-13F6 is an integrated ESD, overvoltage and overcurrent protection with an integrated input rectification bridge to give flexibility for wearable and IoT customers to manage properly any kind of USB charging conditions with or without USB cable inversion.
Thanks to state of the art high voltage technology, ST can integrate in WLCSP package all required USB stressful high voltage and high current protection conditions (ESD, OVP and OCP) with control signals for wearable and IoT design optimization.
所有功能
- USB interface protection between cable and charging circuit during battery charging with:
- Exceeds ESD IEC 61000-4-2 level 4 protection on cable side: ±15 kV contact on bridge inputs, ±12 kV contact on USB data-lines inputs
- Detection of the polarity of the charging cable with rerouting in case of cable inversion thanks to 13 V input rectification bridge
- Overvoltage protection (OVP) up to ± 13 V
- Over current protection (OCP) externally adjustable from 100 mA to 500 mA
- Controlled inrush current
- Over temperature protection
- Under-voltage lockout
- 5 V USB 2.0 data lines protection and multiplexer for data line polarity correction (RON = 6 Ω typical)
- FLAG output signal (open-drain) available to inform thermal shutdown or overvoltage or overcurrent or uncompleted start-up phase
- Proposed in 400µm pitch WLCSP package 13 bumps
- Operating temperature from -30°C to 65°C
