The five regulator outputs are a 10 V at 350 mA (REG1), an 8.5 V at 175 mA (REG2), a 5 V at 350 mA (REG3), an 8 V/1 0V at 1 A (REG4), and 5 V at 250 mA (REG5). The regulators are low dropout. The regulators will operate with output capacitors with ESR of 0.1 Ω to 5 Ω. REG3 is referenced from the VREF input not the internal bandgap. This is done to minimize the voltage offset between individual 5 V supplies. The REG2 and REG3 outputs are turned on and off with the Enable input, a '1' turns the outputs on and a '0' turns them off. When Enable is "1", the other outputs can be independently controlled via the I2C bus. When a given regulator is turned off it must be guaranteed to be lower than 0.2 V. The output voltage of REG4 is selected via bit 5 of the I2C data byte: 8 V is the output voltage if bit5 = '0' while 10 V is the output voltage when bit5 = '1'. When all outputs are turned off the total current draw must be minimized. I2C will run at a clock speed range of 100 kHz to 400 kHz. This device should be capable of operating at any frequency within this range. ) s ( ct u d o 3.1 r P e t e l o Protection s b O The L5954 can survive under the following conditions: shorting the outputs to BAT and GND, loss of BAT, loss of IC GND, double battery, ESD, 34V load dump. L5954 will not handle a reverse battery condition. External components must be implemented for reverse battery protection. ) (s t c u 3.1.1 Thermal shutdown REG1, REG2, REG3, REG4, REG5 outputs shutdown at 160 °C and return to normal operation at 130 °C. The HSD2 and HSD3 shutdown at 160 °C and return to normal operation at 130 °C. The HSD1 with go into thermal shutdown at 170 °C and returns to operation at 120 °C. d o r t e l o 3.1.2 bs O 3.1.3 P e Current limiting Each voltage regulator will contain its own current protection. Short circuit If the outputs are short circuited, the IC will go into current limiting and eventually the thermal shutdown will kick in. Current limiting will not disable the outputs. 10/15 Doc 17717 Rev 1 L5954 Functional description 3.1.4 Overvoltage The IC will not operate if the BAT voltage reaches 27 V typ. or above.
