R1012-15 Datasheet
R1012-15 Price NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. R1012-15 on stock Gate-charge losses are dissipated in the lC, and do not heat the MOSFETs. Ensure that both MOSFETs are at a safe junction temperature by calculating the temperature rise according to package thermal-resistance specifica- tions. The high-side MOSFET's worst-case dissipation occurs at the maximum output voltage and minimum input voltage. For the low-side MOSFET, the worst case is at the maximum input voltage when the output is short- circuited (consider the duty factor to be 100%). In transmit mode the NKM2401 receives eight bytes of serial data from the sending host. It stores this data in a local buffer and then calculates a CRC (Cyclic Redundancy Check) checksum on the data only. It then sets the Transmit Enable line high to enable the RF transmitter module and a 'busy' line high to indicate that no more data can be received. A pre-amble character is sent on the Transmit Data line followed by a special synchronising character, the eight bytes of data and the CRC result. The complete packet of transmitted data is Manchester encoded for optimum transmission over the RF link. |
