Figure 1a shows a latching circuit based on an optocoupler, IC 1. If the off switch remains closed, pressing the on switch powers the LED in the optocoupler. Thus, the transistor in IC 1 turns on. You ...

Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...

In a paper published Tuesday in the Journal of Applied Physics, a group of HP scientists demonstrated what could be a working replacement for today's transistors. Called a "crossbar latch," it is a ...
