DESCRIPTION

· The KTS1640Q and KTS1641Q are low-resistance, electronically controlled load switches with enhanced protection features, designed to safeguard loads from abnormal power supply or load issues. They operate within a wide input supply voltage range of 6V to 40V and provide reverse input supply protection down to -28V. These devices integrate two N-Channel MOSFETs and include fixed over-voltage protection of 27V (KTS1640Q) or 20.3V (KTS1641Q), along with over-temperature protection featuring auto-retry. An ENABLE pin allows for enabling or disabling the MOSFET switch, placing the device in a low current shutdown mode. System monitoring is facilitated by a fault FLAG, and the BDET pin indicates the connection of the battery or power supply. The devices are fully ESD protected and are packaged in a TDFN44-12 package.
