Subsequent charges to P1 and P2 do not change the output voltages unless the supply power is cycled, or all EN inputs are simultaneously driven low to shutdown the device. Shutdown (EN1, EN2) The BD7003NUX, BD7004NUX have independent shutdown control inputs, EN1 and EN2. Driving both EN1 and EN2 low will shut down the entire device, reducing supply current to 1μA max. Connecting EN1 and EN2 to a logic-high or VIN will enable the corresponding output(s). It is prohibited to open EN1, EN2 switches. |
