Abstract
Methods and apparatus for transmitting signals that are magnetically latched at a receiver. In embodiments, a signal isolator comprises a transmitter and a receiver on separate die. Signal disruptions may be minimized. In embodiments, the transmitter and/or receiver can be monitored for proper operation.
Claims26
A signal isolator, comprising:
- a transmitter comprising:
- a transmit module to receive an input signal;
- and
- a transmit current latching module to magnetically latch an output of the transmit module;
- and
- a receiver comprising:
- a receive module including a receiver magnetic field sensing element to detect and magnetically latch a signal from the transmit current latching module.

A method of communicating signals from a transmitter to a receiver isolated from the transmitter, comprising:
- employing a transmitter having a transmit module to receive an input signal and a transmit current latching module to magnetically latch an output of the transmit module;
- and
- employing a receiver having a receive module including a receiver magnetic field sensing element to detect and magnetically latch a signal from the transmit current latching module.
A signal isolator, comprising:
- a transmitter comprising:
- a transmit means to receive an input signal;
- a transmit current latching means to magnetically latch an output of the transmit means;
- and
- a receiver comprising:
- a receive means including a receiver magnetic field sensing means for detecting and magnetically latching a signal from the transmit latching means.
