TPL8556Q数据手册3PEAK中文资料规格书

描述 Description

The TPL8556Q series comprises wide-input LDO products with an integrated watchdog timer, capable of delivering up to 500 mA. These devices can operate within a voltage range from 4 V to 42 V, with a maximum transient voltage of 45 V. Their ability to function reliably with a minimum voltage of 4 V makes them suitable for cold-crank and start-stop scenarios.

The TPL8556Q series offers 5-V and 3.3-V fixed output voltage options, with a maximum shutdown current of only 2 μA. When the watchdog function is disabled, these devices have a low typical quiescent current of just 6 μA.

The TPL8556Q series features the window watchdog and the standard watchdog with an accurate watchdog period. The watchdog period, the window ratio, and the power-good reset threshold are fully adjustable through external configuration. Furthermore, these devices include integrated over-current and over-temperature protection. In terms of output capacitors, the TPL8556Q series is compatible with a broad range from 4.7 μF to 500 μF with an ESR range spanning from 0.001 Ω to 20 Ω.

With the features above, the TPL8556Q series is an ideal power supply for microprocessors in a reliable system.

The TPL8556Q series of products operate in the ambient temperature range from –40°C to +125°C. Additionally, the TPL8556Q series provides a thermal-enhanced ETSSOP28 package to enable sustained operation despite significant dissipation across the device.
