Instructions

L5951 is an integrated single -chip triple regulator using advanced multi -power BCD technology, and the SAE J1850 integrated drive/receiver uses. It is used to drive a single -line J1850 communication, providing micro -controller power and power management for automotive or industrial applications.

function description

General features

L5951 are an integrated circuit, which provides a J1850 physical layer and three voltage regulator Essence This L5951 was developed for microcontrollers to provide power and 2/IDR interfaces.

REG1 output voltage

The output of the reg1 regulator is equal to 3.3V. 3.3V regulator is non -low -voltage drop, which can handle the current to 100mA, and the short -circuit current is limited to 280mA.

REG2 output voltage

REG2 regulator output is equal to 5V, which can process a current of up to 100mA, and the short -circuit current is limited to 280mA. The output level of the 5V regulator is a low voltage difference.

REG3 output voltage

REG3 regulator output is equal to 7.8V, which can process a current of up to 100mA, and the short -circuit limit is 280 mAh. The output level of 7.8V regulator is a low voltage difference. REG3 regulator is controlled by EN control (enabled) IC pins. By switching EN pins, you can open and close the REG3. The logic ""1"" on the EN pin enables REG3, and the logic ""0"" on the EN pin disables REG3. The maximum voltage when REG3 is turned off must be less than 0.2V. Sleep*Enter-2-level transmitter can passSleep*pins open and close. Once the voltage level is higher than the 2 volt DC power, the transmitter is enabled. If the Sleep*pin is less than 0.8VDC and EN is ""0"
