The L9838 is a quad low side driver for lines, lamps or inductive loads in automotive and indus- trial applications. All INputs are TTL or CMOS compatible. This al- lows the device to be driven directly by a micro- controller. For the noise immunity, all inputs have a Schmitt-trigger with a hysteresis of typ. 100mV. Each input stage has an input voltage protection from -24V to 45V. The device can be activated with a ’high’ signal on ENable input. ENable ’low’ switches the device into the sleep mode. In this mode the quiescent current is less than 10µA. A high signal on PRoGramming input changes the signal transfer polarity from noninverting into the inverting mode. Normally this pin is connected to V S or GND. These pins (PRG and EN) are inter- nally fixed at low status by open input condition. Independent of the PRoGramming input, the OUTput switches off, if the signal INput pin is not connected. Each output driver has a current limitation of min 0.4A and a seperate thermal shut-down. The ther- mal shut-down deactivates that output which ex- ceeds Temperature switch off level. About 20K below this temperature threshold the output will be activated again. This means, that each output is able to sink continuously 285mA without acti- vating thermal shut-down at 85°C ambient tem- perature (SO20). The slew rate of the output is limited to max. 14V/µs to reduce the electromag- netic interference, but not for the enable transfer characteristic (see fig. 1). An integrated active fly- back voltage limitation clamps the output voltage during the flyback phase of inductive loads to typ. 50V. The power DMOS switches ON, if the device is enabled and the OUTput swings below ground. This protection avoids the activation of parasitics inside the power DMOS. The DIAGnostic is an open drain output. The logic status depends on the PRoGramming pin. If the PRG pin is ’low’ the DIAG output becomes low, if the device works correctly. At thermal shut-down of one channel, discon- nected ground or supply voltage the DIAGnostic output becomes high. If the PRG pin is ’high’ this output is switched off at normal function and switched on at overtemperature.
