114 / 126 page  Electrical Characteristics L9803 114/126 7 Electrical Characteristics 7.1 Absolute Maximum Ratings This device contains circuitry to protect the inputs against damage due to high static voltage or electric fields. Nevertheless, it is recommended that normal precautions be observed in order to avoid subjecting this high-impedance circuit to voltage above those quoted in the Absolute Maximum Ratings. For proper operation, it is recommended that the input voltage VIN, on the digital pins, be constrained within the range: (GND - 0.3V) ≤ V IN ≤ (VDD + 0.3V) To enhance reliability of operation, it is recommended to configure unused I/Os as inputs and to connect them to an appropriate logic voltage level such as GND or VDD. All the voltage in the following tables are referenced to GND. Table 16. Absolute Maximum Ratings (Voltage Referenced to GND) Symbol Ratings Value Unit VBR VBL = VB VB1 Operating Supply Voltage t = 10s ISO transients t = 400ms(1) 1. ISO transient must not reset the device 0 to 18 0 to 24 0 to 40 V VBR=VBL Dynamic Destruction proof t<500us (single pulse) 0 to -2 V |AGND - GND| Max. variations (Ground Line) 50 mV T STG Storage Temperature Range -55 to +150 °C T J Junction Temperature 150 °C ESD ESD susceptibility 2000 V V LV Input Voltage, low voltage pins GND - 0.3 to V DD + 0.3 V V PWM Pin Voltage, PWMI, PWMO pins GND - 18 to VB V V CAN Pin Voltage, CAN_H, CAN_L pins GND - 18 to VB V IIN Input Current (low voltage pins) -25.....+25 mA |
