The LDC0851 is a low-cost inductive comparator, generating an output based on the difference between a sense inductor and a reference inductor. A pair of resistors on the ADJ pin can be used to adjust the sensitivity or switching distance; no other configuration is necessary. The LDC0851 uses one capacitor for both sensors, which improves the matching of the two sensors and also reduces system cost. The LDC0851 does not have any registers and therefore does not require any MCU configuration for operation.
The main features of this device include:
The sensor drive design of the LDC0851 makes it able to drive nearly any sensor within its design requirements (based on the sensor L and the sensor C), without needing to consider the sensor RP.
