L9333 FUNCTIONAL DESCRIPTION The L9333 is a quad low side driver for lines, lamps or inductive loads in automotive and industrial applications. The logic input levels are 3.3V CMOS compatible. This allows the device to be driven directly by a microcontroller. For the noise immunity, all input thresholds have a hysteresis of typ. 100mV. Each input (IN, EN and PRG) is protected to withstand voltages from -14V to 45V. The device is activated with a 'high' signal on ENable.

L9333 EMC SPECIFICATION EMS (electromagnetic susceptibility) Measurement setup: DUT mounted on a specific application board is driven in a typical application circuit (see below). Two devices are stimulated by a generator to read and write bus signals. They will be monitored externally to ensure proper function. Measurement method: a) The two bus lines are transferred 2m under a terminated stripline. That's where they were exposed to the RF-field.
