5. Functional description

A diagnostic status ensures faster fault detection. Active current limit is combined with a soft latched short circuit protection feature in

order to protect the device in the event of a short circuit. Thermal shutdown for high temperature conditions has an automatic restart at a

lower temperature so providing protection against excessive power dissipation. Active clamping protects the device against low energy spikes. Undervoltage lockout means the device shuts down for low battery voltages, thus

avoiding faulty operation. Overvoltage shutdown in the on-state protects a load such as a lamp ﬁlament from

potentially destructive voltage spikes.

[1] The device will not be harmed by exposure to the maximum supply voltage, but normal operation isnot possiblebecause of overvoltage

shutdown - see Table 7 “Static characteristics” for the operating range.

[2] Reverse battery voltage is only allowed with external resistors to limit the input and status currents to a safe value. The connected load

must limit the reverse load current. The internal ground resistor limits the reverse battery ground current. See Figure 10 “Typical

dynamic response circuit diagram including reverse supply protection and open load detection.”
