MAX20323, MAX20323C, MAX20323D, MAX20323F

USB Type-C CC-Pin Overvoltage Protector

Protect the CC (or SBU) Lines in USB Type-C from a High-Voltage Short or Surge Event

Product Details

The MAX20323, MAX20323A, MAX20323B, MAX20323C, MAX20323D, MAX20323E, MAX20323F overvoltage protectors feature internal overvoltage threshold and surge protection to turn off the switches and prevent damage to USB type-C CC/SBU pins.

The devices have two channels switches with 0.27Ω (typ) on-resistance that are turned on when inputs are below overvoltage threshold. When overvoltage threshold is exceeded on one of the channels, the corresponding switch is turned off and replaced by an accurate pullup current to output (CC1_O/CC2_O) that is sourced from input (CC1_I/CC2_I). (The MAX20323A/C/F does not have pullup current feature).

The devices are available in a 12-bump (0.4mm pitch, 1.7mm x 1.32mm) WLP package and operate over the -40°C to +85°C extended temperature range.

Key Features

  • Flexible System Design
    • Wide Operating Supply Voltage Range: 2.5V to 5.5V
    • Integrated 270mΩ (typ) Switch per Channel with 1A Continuous Current Capability
    • Low Supply Current of 20µA (typ) when CC Inputs Are Under Overvoltage Threshold
    • Accurate Pullup Currents to CC Outputs When CC Inputs Exceed Overvoltage Threshold (Except MAX20323A/C/F)
  • Reliable Protection
    • Accurate OVLO Threshold: 5.75V±0.2V
    • Surge Immunity:
      • MAX20323/A/B: Over ±90V
      • MAX20323C/D/E/F: &plusmn80V with No VENCC or &plusmn60V with Valid VENCC
    • Ultra Fast Turn Off: 100ns (typ) Response Time
    • Thermal Shutdown Protection
  • Space Saving
    • 12-Bump 0.4mm Pitch 1.7mm x 1.32mm WLP

Applications/Uses

  • Industrial PCs
  • Phablets
  • Smart Phones
  • Tablets
