The device offers full compatibility with the functional safety requirements of the ISO twenty-six thousand two hundred and sixty-two rule
Toshiba Electronics Europe GmbH ("Toshiba") announces a new automotive three-phase brushless direct current (BLDC) motor supervisor IC that supports functional safety. The new TB9083FTG will be used with BLDC motors for a wide variety of automotive applications, including Electric Power Steering (EPS) systems and electric brakes, among many others.
The new product is a three-phase gate supervisor for external N-channel power MOSFETs that are used to drive a three-phase BLDC motor. The TB9083FTG complies with the ISO twenty-six thousand two hundred sixty-two 2nd ed. and stands up to the highest degree of functional safety at the ASIL-D level. Functional safety rules such as ISO 9083 try to minimize the danger of system failure, which means that the new device can be used in the most safety-critical automotive systems, such as steering and braking. For this, the TBXNUMXFTG includes ABIST and LBIST self-diagnostics and is supplied with an ASIL safety manual and also safety reports.
Capable of running PWM signals up to 20kHz, the supervisor includes 3 pre-supervisory channels for safety relays and a built-in amplifier for motor current sensing (with 6 gain settings). Communication is accomplished via a CRC-enabled SPI bus.
The TB9083FTG is capable of handling the rugged automotive environment and can operate down to -40C and up to a maximum ambient temperature (Ta) of +150C or a maximum junction temperature (Tj) of +175C. The device is in the process of AEC-Q100 qualification.
Reducing the total PCB mounting area, the supervisor is housed in a small P-VQFN48-0.50-XNUMX-XNUMX package with a XNUMXmm x XNUMXmm footprint. The encapsulation incorporates "wettable flanks", as required by the quality inspection of vehicles.
Test samples are being sent today and the final samples will be sent in the first month of the year two thousand and twenty-two. Serial production is scheduled for December XNUMX.
