MAX22700D–MAX22702D Ultra-High CMTI MAX22700E–MAX22702E Isolated Gate Drivers General Description Benefits and Features
The MAX22700–MAX22702 are a family of single-chan- ● Matching Propagation Delay nel isolated gate drivers with ultra-high common-mode • 20ns Minimum Pulse Width transient immunity (CMTI) of 300kV/µs (typ). The devices • 35ns Propagation Delay at Room Temperature are designed to drive silicon-carbide (SiC) or gallium- • 2ns Part-to-Part Propagation Delay Matching at nitride (GaN) transistors in various inverter or motor Room Temperature control applications. All devices have integrated digital • 5ns Part-to-Part Propagation Delay Matching over galvanic isolation using Maxim’s proprietary process tech- -40°C to +125°C Temperature Range nology. The devices feature variants with output options ● High CMTI (300kV/µs, typ) for gate driver common pin GNDB (MAX22700), Miller ● Robust Galvanic Isolation clamp (MAX22701), and adjustable undervoltage-lockout • Withstands 3kVRMS for 60s (VISO) UVLO (MAX22702). In addition, variants are offered as • Continuously Withstands 848VRMS (VIOWM) differential (D versions) or single-ended (E versions) • Withstands ±5kV Surge Between GNDA and VSSB inputs.

for details. All of the devices in the MAX22700–MAX22702 family are available in an 8-pin, narrow-body SOIC package with 4mm of creepage and clearance. The package material has a minimum comparative tracking index (CTI) of 600V, which gives it a group I rat ing in creepage tables. All devices are rated for operation at ambient temperatures of -40°C to +125°C. 19-100581; Rev 2; 9/19
