Functional Description

The TLE 4290 is a monolithic integrated low drop voltage

regulator which can supply loads up to 450 mA with

power good feature. An input voltage up to 42 V is

regulated to

Q,nom

= 5.0 V. The device is designed to

supply μ-controllers in the severe environment of

automotive applications. Therefore it is protected against

overload, short circuit and over temperature conditions. Of course the TLE 4290 can

been used also in all other applications, where a stabilized 5 V voltage is required.

TLE 4290 Power Good The Power Good PG pin informs e.g. the microcontroller in case the output voltage has fallen below the lower threshold VQ,pgt-d of typ. 3.65 V. Connecting the regulator to a battery voltage at first the power good signal remains LOW. When the output voltage has reached the higher threshold VQ,pgt-i the power good output remains still LOW for the power good delay time trd. Afterwards the power good output turns HIGH.

TLE 4290 The power good circuit supervises the output voltage. In case VQ falls below the Power Good switching threshold the Power Good output PG is set LOW after the power good reaction time. The power good LOW signal is generated down to an output voltage VQ to 1 V. A LOW signal at the power good pin informs that the battery was lost and memory is no longer valid. The feature should only be used in combination to a microcontroller with internal reset.

TLE 4290 The power good reaction time trr is the time it takes the voltage regulator to set power good output PG LOW after the output voltage has dropped below the power good switching threshold. It is typically 0.5 μs for delay capacitor of 47 nF. For other values for CD the reaction time can be estimated using the following equation: trr = 10 ns/nF × CD (2) The Power Good output is an open collector output. It requires externally a pull-up resistor of at least 5 kΩ to Q. Data Sheet 10 Rev. 1.
