PRODUCTION DATA
The diagnostic enable pin, DIAG_EN, offers multiplexing of the microcontroller diagnostic input for current sense or digital status, by sharing the same sense resistor and ADC line or I/O port among multiple devices.
In addition, during the output-off period, the diagnostic disable function lowers the current consumption for the standby condition. The three working modes in the device are normal mode (IQ), standby mode (ISTBY), and standby mode with diagnostic (IDIA). If off-state power saving is required in the system, the standby current is < 500 nA with DIAG_EN low. If the off-state diagnostic is required in the system, the typical standby current is around 1 mA with DIAG_EN high.
