The input to both switches is protected against VBUS surge voltages of up to \u00b1100V, and is also protected against over-voltage, with preset trip points on both the VBUS to OUT and VBUS to SYS paths, providing protection to downstream components from abnormal input conditions.<\/p>\n<p>The main switch (VBUS to OUT) features a unidirectional active-LOW enabled 3.5A rated MOSFET, with an OVP trip point of 13.9V \u00b1400mV. The secondary switch (VBUS to SYS) is an active-HIGH enabled, reverse-blocking 6.0A rated MOSFET, with an OVP trip point of 5.25V \u00b1250mV. The input to both switches is rated up to a maximum of 28V.<\/p>\n<p>When VBUS is greater than 2.7V, the POK LDO provides an \u201calways ON\u201d power source, regardless of the OVLO, EN1 \u0305\u0305\u0305\u0305\u0305\u0305 and EN2 state, to power downstream components permitting operation without an installed battery.<\/p>\n<p>The KTS1678B also features an active-HIGH SHUTDOWN pin to conserve power, plus over-temperature thermal protection.<\/p>\n<p>The KTS1678B is packaged in advanced, fully \u201cgreen\u201d compliant, 2.96mm x 1.67mm, Wafer-Level Chip-Scale Package
