TPS1HB16-Q1: Reverse battery and startup

Hi Inderjit Bains, 

1- Other devices within our portfolio that can do reverse current blocking are the eFuses and Ideal diodes. However, for driving capacitive loads we recommend a device that can clamp the current at certain limits while delivering the inrush current demanded by the capacitors. 

2- Out portfolio is composed of devices that can either provide a current clamp at a certain level or a device that will instantly shut down. For driving a capacitive load we recommend devices that can provide a current clamp in order to securely charge the capacitors. Note, that even devices with a current clamp can reach a shutdown due to integrated thermal protection. If the device temperature rises above the preset threshold, the device will reach a thermal shutdown. In the case of the TPS1HB16, the device was designed for an instant shutdown. Other devices in our portfolio such as the TPS1HA08 has multiple versions that will allow for either feature.
