11 / 30 page TLE 6209 R Data Sheet, Version 3.1 11 2007-08-01 thresholds. As soon as a threshold is reached, the according status bits are set in the SPI diagnosis word (c.f. Table 5). If the overtemperature shutdown threshold is reached, the output stages are turned off. The temperature monitoring messages and the over temperature shutdown are latched and can be reset by the status register reset bit 7 of the SPI control word or a POR. 2.5.6 Power Supply Fail The power supply Voltage is monitored for over- and under voltage lockout: • Under Voltage Lockout If the supply voltage V S drops below the switch off voltage VUV OFF, all output transistors are switched off and the power supply fail bit (bit 7 of the SPI diagnosis word) is set. If V S rises again and reaches the switch on voltage VUV ON, the power stages are restarted. The error bit, however, is latched and has to be reset by the status register reset bit 7 of the SPI control word. • Over Voltage Lockout If the supply voltage V S rises above the switch off voltage VOV OFF, all output transistors are switched off and the power supply fail bit (bit 7 of the SPI diagnosis word) is set. If V S falls again and reaches the switch on voltage VOV ON, the power stages are restarted. The error bit, however, is latched and has to be reset by the status register reset bit 7 of the SPI control word. The OVLO is only active if control bit 6 is H. If the bit is low, the OVLO is deactivated. 2.5.7 Error Flag Bit 0 of the SPI diagnosis word is an OR of the status bits 1 to 7. It can be read out without full SPI communication as described in Figure 8. |
