Halo Microelectronics’ HL5097 provides protection for input voltages of up to 28 V for USB Type-C connectors used in smartphones and mobile IoT devices, with surge protection at up to ±40 kV. This high-performance switch IC offers two-channel operation with fixed over-voltage thresholds of 5.8 V and 4.8 V for the Configuration Channel (CC) or Sideband Use (SBU) interface IC options respectively.
The HL5097 is designed for VSYS voltages of 2.5-5.5 V and VBUS voltages up to 20 V. The N-MOS switching architecture features a low Rds(on) of 160 mΩ with the ability to deliver currents of up to 1.25 A, and it also boasts a 30-ns response time for fast protection against overvoltage events. The device also supports dead battery operation, where an internal pull-down resistor will terminate input signals to ground and switch to operating the end device using the VBUS power supply. Additionally, IEC 61000-4-2 system-level ESD protection for the input signal pins is integrated within the HL5097, removing the requirement for external high-voltage Transient-Voltage-Suppression (TVS) diodes in your design.
Halo Microelectronics’ USB Type-C protection IC is available in a 6–pin, 1.25 x 0.93 mm WLCSP package with an operating temperature range of −40°C to 85°C. For more information on the HL5097, please consult this official product brief.
