TLS208D1LDV

The TLS208D1 is especially designed for applications with a permanent connection to pre-regulators like DCDC converters. The device is available in the small surface mounted PG-DSO-8 (Exposed Pad) and TSON-10 packages. In addition to the enable functionality, the feature set includes a reset with an adjustable reset threshold. This threshold can be modified by an external resistor divider. The device is designed for the harsh environment of automotive applications. Therefore it is protected against overload, short circuit and over-temperature conditions by the implemented output current limitation and the over-temperature shutdown circuit. The input capacitor C I is recommended for compensating line influences. The output capacitor C Q is necessary for the stability of the regulating circuit.
