DESCRIPTION
L9825 is a Octal Low-Side Driver Circuit, dedicated for automotive applications. Output voltage clamping is provided for flyback current recirculation, when inductive loads are driven. Chip Select and Serial Peripheral Interface for outputs control and diagnostic data transfer. Parallel Control inputs for two outputs.
■ OUTPUTS CURRENT CAPABILITY UP TO 1A, RON ≤ 0,75Ω AT TJ = 25°C
■ PARALLEL CONTROL INPUTS FOR OUTPUTS 1 AND 2
■ SPI CONTROL FOR OUTPUTS 1 TO 8
■ RESET FUNCTION WITH RESET SIGNAL AT NRES PIN OR UNDERVOLTAGE AT VCC
■ INTRINSIC OUTPUT VOLTAGE CLAMPING AT TYP. 50V
■ OVERCURRENT SHUTDOWN AT OUTPUTS 1 TO 6
■ SHORT CIRCUIT CURRENT LIMITATION AND SELECTIVE THERMAL SHUTDOWN AT OUTPUTS 7 AND 8
■ OUTPUT STATUS DATA AVAILABLE ON THE SPI
