Key Benefits

• Wide portfolio of products
• Reduce the need for board space with smaller packaging
• Increased battery life by minimizing quiescent current (I_Q)
• Offers application notes and other material to help with design
• Aids in current protection standards (IEC-62368-1) with eFuse

Power Supply Circuit Solutions

Wireless or contact charging presents design challenges with control and protection from the outside world, whether a short circuit condition or EMI.

Toshiba Load Switches or eFuse IC can provide precise control in addition to over-voltage and over-current protection. These ICs are supported with various FETs and diodes.

Beyond the PMIC, there are requirements for LDOs and switches designed for rails leading to sensitive sensors, chipsets, and other modules. Performance is maximized by implementing low I_Q load switches and LDOs in tiny wafer-level chip-scale packages.

Interface Circuit Solutions

Another consideration is the interface side of any design. This involves the subsystem which manages sensor outputs and controls displays or wireless modules.

Sensors are becoming increasingly smaller, requiring ultra-low offset voltage and low noise op-amps to help bring the recorded signal to a readable level. Toshiba offers op-amps to address both of these requirements.

In addition, Toshiba offers high-speed and high-current ESD protection diodes to help manage unwelcome static shock, a concern when designing wearables and other handheld devices. This feature is achieved with minimal insertion loss, allowing for speeds up to 10Gbps.
