USB Charge Protection IC | New product new technology

Expand! Add USB charge functionality to your sets! Simply connect Safe Charge IC Series (USB Charge Protection IC)

Overview

An increasing number of portable devices utilize USB for data communications and battery charging. However, countermeasures must be made to safeguard against sudden and unexpected power surges. In answer to this ROHM has developed ultra-compact USB charge protection ICs that make it easy to protect portable electronic devices from abnormal voltages and currents. Simply plug it in.
The BD6046GUL – the newest addition to the lineup – integrates a reverse polarity protection function that prevents inadvertent possible combustion in the event of reverse connection.

Feature 1: Ultra-compact CSP (Chip Scale Package) results in greater space savings

ROHM charge protection ICs integrate a low ON-resistance power switch, charge pump, and multiple protection circuits on a single chip. In addition, their ultra-compact size (chip-scale package) – the smallest in the industry – make them ideal for compact, portable battery-driven USB devices of all types.

Feature 2: ± 30V voltage resistance ensures a high degree of safety during reverse USB connection

The rise in battery charging for portable devices via USB makes it increasingly important to protect against failures and possible injury due to external factors such as connector interface and/or supply capability. ROHM charge protection ICs feature 30V voltage resistance and integrate multiple protection circuits, shutting down power in the event of reverse connection, ensuring a greater degree of safety.
