Silicon Labs TS1110-20DB, Current Sensing Amplifier Demonstration Board for TS1109-20

Demonstration boards for the Silicon Labs TS1110 range. These electronic circuit breakers use a bidirectional current-sensing amplifier to detect the current limit and disconnect the load by using an external P-Channel MOSFET. They have an internal current limit comparator with an adjustable threshold and signal when a fault has occurred. The circuit breaker system has a typical delay of 428 μseconds.

Available in two gain options:
20 V/V - TS1110-20DB (RS 894-7121)

These demo boards are supplied fully assembled and tested. The TS1110 are available in 16-pin TQFN packages.

Current Sensing Amplifiers have a voltage output that is proportional to the volt drop across a very low value resistor, usually in a high-current power rail. Hence they measure the current flowing in that power rail.
