Short circuit protection function

Description: The TPS7A66-Q1 and TPS7A69-Q1 are low dropout linear regulators designed for circuits operating from input voltages up to 40V. With a quiescent current of only 12µA at no load, these devices are ideal for standby microprocessor control unit systems, especially in automotive applications where low power consumption is a key concern.

This device features integrated short-circuit and overcurrent protection. The device performs a reset delay on power-up to indicate that the output voltage is stable and in regulation. The user can program this delay with an external capacitor. The low-voltage tracking feature allows the use of smaller input capacitors and potentially eliminates the need for a boost converter during cold crank conditions.

The device operates over the -40°C to 125°C temperature range. The TPS7A6650EDGNRQ1 device is AEC-Q100 Grade 0 qualified and has an operating temperature range of –40°C to 150°C. These characteristics are well suited for high efficiency, high power density, and robustness requirements in power supplies in a variety of automotive applications.
