Low-Frequency Driver and Receiver IC for Passive Keyless Entry Applications

NJJ29C0BHN

The NJJ29C0 low Frequency (LF) transceiver integrates a 6-channel Class D* LF driver, DC-to-DC boost converter, microcontroller, and the immobilizer reader. The device supports a shared Passive Keyless Entry (PKE)/Immobilizer coil and enables increasingly popular features such as welcome lighting and passive, walkaway locking. NJJ29C0 is designed to seamlessly work with NXP's advanced transponder, microcontroller, and radio transmitter technologies, completing NXP's portfolio of full solutions for Secure Car Access systems. Remote access applications based on NXP's full system solutions also deliver good security.
