The 40V “TCKE6 series” products have been added to Toshiba Electronic Devices & Storage Corporation’s line of electronic fuses (eFuse ICs) that offer various functionalities needed for power line circuit protection.
The New TCKE6 Series eFuse ICs Offer:
- Short-circuit protection similar to that of standard physical fuses while also incorporating current limiting and overvoltage protection functions.
- Capabilities that physical fuses cannot provide and that protect circuits from overcurrent and overvoltage.
- These features help to prevent excessive current or voltage from being applied to subsequent ICs when overcurrent or overvoltage occurs at a point in a circuit.
- The eFuse ICs also have a built-in thermal protection function that immediately shuts them down when abnormal heat is generated or an unexpected short-circuit occurs. thereby protecting the subsequent circuit.
- An additional advantage of eFuse ICs is simplified circuit design.
- By integrating multiple protection functions into a single device, they reduce the need for discrete components, enabling more compact and efficient designs with fewer parts and a smaller footprint.
The TCKE6 Series Products Feature:
- 40V rating and support a wide input voltage range from 4.4V to 30V,
- Making them suitable for power management applications, such as 5V, 9V, 12V, and 24V systems.
- A low on-resistance of 52m? (typ.) reduces power dissipation during operation and contributes to improved efficiency.
- The devices are housed in a small TSOP6F package (2.9mm×2.8mm (typ.)), which helps to reduce board size.
- These eFuse ICs are suitable for a wide range of applications, including industrial and consumer equipment.
Products in the TCKE6 series have an EN (enable) function that regulates the eFuse IC’s functioning as well as a FLAG function that detects and reports abnormal conditions.
There are two recovery operation types for each function type: latching, which recovers via an external signal, and auto-retry, in which the eFuse IC automatically recovers.
Furthermore, one of the items permits mode switching between auto-retry and latching kinds via external signals but lacks FLAG and EN functionalities. Users can select the best product based on their equipment size and system requirements thanks to this flexibility.
The five new products joining the lineup are “TCKE601RA,” “TCKE601RL,” “TCKE602RM,” “TCKE603RA,” and “TCKE603RL.” Shipments start today.
Toshiba will continue to develop eFuse IC products that meet diverse equipment requirements and expand its product lineup.
