General Description
The MAX20323/MAX20323A/MAX20323B/MAX20323C/
Benefits and Features
● Flexible System Design
MAX20323D/MAX20323E/MAX20323F
overvoltage
• 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/F)
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/F do not have the
pullup current feature).
● Reliable Protection
• Accurate OVLO Threshold: 5.75V±0.2V
• Surge Immunity
• MAX20323/A/B/C/E/F: Over ±90V
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.
• MAX20323D: ±80V with No V
or ±60V with
ENCC
Valid V
ENCC
• Ultra-Fast Turn Off: 100ns (typ) Response Time
• Thermal Shutdown Protection
Applications
