Microcontroller meets needs of modern appliances
Toshiba Electronics Europe has launched a flash microcontroller specifically designed to meet the needs of modern home appliance applications including washing machines, dryers, and dishwashers.
As a result, the devices are ideal for onboard power supplies, programmable controllers, I/O interface boards, and AC adapters for PDAs.
Each of the new devices is based on a design whereby phototransistors that are optically coupled to a gallium arsenide IR emitting diode.
The TLP283 features a single transistor/diode pair in a 4-pin package, while the TLP283-4 integrates four transistor/diode pairs in a 16-pin package.
Respective package dimensions are 4.4 x 2.6 x 1.9 and 4.4 x 10.3 x 1.9mm.
Both the new devices are certified to UL1577 and have a minimum rated isolation voltage of 2.5kV RMS.
Minimum collector-emitter voltage is rated at 100V.
Current transfer ratio is 100%, and maximum pulse delay time is 100us (with a forward current of 1mA and a load of 10kohm).
The TLP283 and TLP283-4 will operate at temperatures ranging from -55 to +100C.
