10.4 Power Supply Recommendations

The TPS1HB35-Q1 device is designed to operate in a 12-V automotive system. The nominal supply voltage range is 6 V to 18 V as measured at the VBB pin with respect to the GND pin of the device. In this range the device meets full parametric specifications as listed in the Electrical Characteristics table. The device is also designed to withstand voltage transients beyond this range. When operating outside of the nominal voltage range but within the operating voltage range, the device will exhibit normal functional behavior. However, parametric specifications can not be specified outside the nominal supply voltage range.

Table 10-8 Operating Voltage Range
VBB VOLTAGE RANGE NOTE
3 V to 6 V Transients such as cold crank and start-stop, functional operation are specified but some parametric specifications can not apply. The device is completely short-circuit protected up to 125°C.
6 V to 18 V Nominal supply voltage, all parametric specifications apply. The device is completely short-circuit protected up to 125°C.
18 V to 40 V Transients such as jump-start and load-dump, functional operation specified but some parametric specifications can not apply.
