The MSC interface can be single ended or low voltage differential type. Serial transmission of the error code (diagnostic) via MSC interface (upstream channel). All power stages (PS) are protected against short circuit to battery voltage (SCB). All PS (OUT1...18) are equipped with switch off mode and current control mode in case of SCB (configurable). Diagnosis of open load (OL), short-circuit to ground (SCG), short-circuit to battery voltage (SCB) and over temperature (DOT) individually for each PS. The fault conditions SCB, SCG, OL and DOT are not stored until an integrated filtering time has expired. If, at one output, several errors occur in a sequence, always the last detected error is stored (after filtering time). All fault conditions are encoded in two bits per stage and stored in the corresponding MSC interface registers. Additionally there is one common diagnostic bit for fault occurrence (FAILURE_FLAG) at any output and one common diagnostic bit (COTW) for diagnosis over temperature (DOT). The diagnostic registers can be read via MSC interface. During the start-bit of a read out cycle the corresponding diagnostic register is cleared, nevertheless the status of the diagnostic register before the start-bit is send. Pull-down Diagnostic currents and Open Load OL can be switched off by configuration for OUT11...18; (CONREG3 and OUT1516). Each stage (OUT1...14, 17, 18) is controlled with a separate bit of the data frame (downstream channel). The control bit is non inverting, i.e. if a control bit is ‘1’ the corresponding stage is off. Stages are disabled – i.e. switched off and switching on disabled if VDD is too low (VDD undervoltage or power on reset) or VDD too high (VDD overvoltage). The same applies when the MSC monitoring detects an error, micro controller reset is active (i.e. external signal on pin RST = low or external signal on Pin ABE is logical low level). All outputs are designed with internal zener diodes for applications with inductive loads. OUT1 and OUT3 are designed for normal operation with 4A and extended current of 8A for maximum of 200 seconds each vehicle driving cycle. OUT5...OUT10 are disabled by active low level on pins DIS5_10 (with short delay). OUT9 and OUT10 are designed for actuators with higher clamping energy. OUT15 and OUT16 can be forced OFF with the higher thresholds of DELAYIN (VDELAYIN_RES15_16_L and VDELAYIN_RES15_16_H) (see Figure 8). OUT15 and OUT16 can be configured to delayed reset behavior, in this case, the switching-off algorithm is delayed by internal filtering time (exception: power on reset (POR), RES15_16 and valid command frame to switch off stages is not delayed). Parallel connection of stages (OUT1...14, 17, 18) is possible as the control bits that switch on and off these stages are all transmitted in the same data frame. OUT15 and OUT16 are only allowed to be connected to each other and not to other stages (see Chapter 5.10). DELAYOUT is pulled active low to switch off external components by the lower thresholds of DELAYIN (VDELAYIN_L and VDELAYIN_H), ABE or VDD monitoring.

The specific function of the channel group OUT15,16 is described in Chapter 5.7. The reset input of the OUTn-control flip-flop is active high and dominant, delivering a logic low level at the output of the OUTn-control flip-flop.Only in failure-free condition, output can be switched on by MSC downstream. Disabling inputs DIS5_10 and DELAYIN have different input characteristics and delay (tDELAYIN >> tDIS5_10). For details concerning DIS5_10, DELAYIN and DELAYOUT see Chapter 7 and Figure 1. 5.2 Power Stages OUT1 and OUT3 Table 7 Electrical Characteristics Power Stages OUT1 and OUT3 n = 1 and 3, all channels ON or OFF, nominal load conditions, 4.5V < VDD < 5.5V, 4.5V < VBAT < 40V, all voltages with respect to PGND, positive current flowing into pin.
