Toshiba launches automotive photocoupler with 900V output
Summary
The TLX9152M features a minimum output withstand voltage (VOFF) of 900V to support applications such as battery and fuel-cell control, as well as battery management systems (BMS) in electric vehicles (EV) where it can be used in circuits to monitor voltages, monitor for mechanical relays sticking and to detect ground faults. Its fast reaction (TON/TOFF) time of 1ms (max) is a critical decisive specification for design engineers. Moreover, the off-state current (IOFF) of this device is 100nA (max) at ambient temperature, meaning that it draws minimal power while inactive. When used in 1kV systems, this normally-open (1-Form-A) device exhibits 5mm creepage and clearance distances on its output side, ensuring that effective isolation is maintained. The device is capable of operating across a wide temperature range from –40° to +125°C, and is fully qualified according to the AEC-Q101 standard for automotive applications.
