t KTS1680A Overvoltage Protected Load Switch with Surge Protection Features Brief Description Surge and ESD protected Input The KTS1680A overvoltage protection device features an Surge Protection ultra-low 28m (typical) on-resistance high current IEC 61000-4-5: > 100V integrated MOSFET which actively protects low-voltage ESD Protection systems from voltage supply faults up to +28V . An DC IEC 61000-4-2 (Level 4) internal clamp protects the device from surges up to 100V. Contact: 8kV An input voltage exceeding the overvoltage threshold will Air Gap: 15kV cause the internal MOSFET to turn off, preventing Human Body Model: 2kV excessive voltage from damaging downstream devices. Wide Input voltage range When the OVLO input set below the external OVLO select 2.3V to 28V voltage, the KTS1680A automatically chooses the internal Low Quiescent Current: 80A (typ.) fixed OVLO threshold, preset to 5.95V (typical). The over- Integrated 28m (typ) N-Channel MOSFET voltage protection threshold can be adjusted with optional Fast turn-off response time resistor divider to a voltage between 4V and 25V. 100ns Flexible trip-point options The device features an open-drain output ACOK indicating Fixed 5.95V a stable supply between the minimum supply voltage and Adj. 4V to 25V OVLO threshold. The KTS1680A is also protected against Auto-enabled switch with typ. 15ms over-current faults and has thermal protection. debounce time The KTS1680A is available in a RoHS and Green Additional Under voltage (UVLO), Short-circuit compliant 12-Bump 1.70mm x 1.21mm x 0.62mm WLCSP. and Thermal shutdown protection Open-drain power good output Pb-free WLCSP34-12 package -40C to +85C Temperature Range Applications Smartphones Tablet Computers Mobile Internet Devices Peripherals Typical Application Battery Adapter/USB IN OUT Battery Charger C V C IN I/O OUT 0.1F 1F KTS1680A PMIC R1 OVLO ACOK Application CTRL Processor R2 GND June 2019 Revision 04a Page 1 Company Confidential t KTS1680A Pin Descriptions Pin Name Function A1 CTRL OUT power path is Enabled when CTRL is logic Low. Output of internal main high-current power switch. Connect OUT pins together in the PCB for A2, A3, B2 OUT proper operation. A4, B4, C4 GND Ground. Connect GND pins together in the PCB for proper operation. Open-drain power good output. ACOK is driven low during normal operation and becomes high B1 ACOK impedance when an out-of-range condition is detected. Connect a pull-up resistor between the logic pin and the system rail. B3, C2, C3 IN Voltage Input. Connect IN pins together in the PCB for proper operation. External OVLO Adjustment. Connect OVLO to GND when using the internal fixed threshold. C1 OVLO Connect a resistor-divider to OVLO to set the adjustable OVLO threshold. The optional external resistor divider is unrelated to the internal threshold.
