ISL8215M-Slide8

An array of protection features is integrated into the ISL8215M which guarantees safe operation under abnormal conditions. These protections include under-voltage lockout (UVLO), thermal, overcurrent or short-circuit, and overvoltage protection. As previously mentioned, the highly integrated ISL8215M provides several configuration settings to optimize operations and performance. One of these being the capability to control the ramp-up of the output voltage and therefore limiting the inrush current. This provides a more reliable and robust design by avoiding current spikes and allows usage of smaller input and output capacitors. The ISL8215M has a default soft-start delay of 1.5ms. If a different delay is required, simply connect a small capacitor to the SS/TRK pin. The ISL8215M output voltage ramp up can also be set up to track a master voltage by simply selecting a resistive divider network applied to the SS/TRK pin.
