Intersil’s ISL6615 and ISL6615A high-frequency 6-A sink synchronous MOSFET gate drivers provide high efficiency, flexibility and special protection features for system safety. The drivers feature increased gate drive currents versus previous-generation devices to reduce gate voltage rise and fall times, minimizing switching losses.
Device type: 6-A sink synchronous MOSFET drivers
Switching frequency: up to 1 MHz
Input voltage range: 5 V to 12 V
Features: 4-A source and sink gate-drive currents for UGATE and 4-A source with 6-A sink on LGATE, support for 3.3-V PWM signals (ISL6615) or 5-V PWM signals (ISL6615A), ability to drive upper and lower gates over a range of 4.5 V to 13.2 V, bootstrap capacitor overcharging prevention, a tri-state PWM input for safe output-stage shutdown, pre-POR overvoltage protection and VCC undervoltage protection
Operating temperature range: 0ºC to 70ºC or -40ºC to 70ºC
Packaging: 8-lead SOICs and 10-lead DFNs
RoHS compliant? yes
Target applications: point-of-load dc-dc converters, core regulators for microprocessors, synchronous rectification for isolated power supplies
Pricing: $1.67 each (SOIC) and $1.69 each (DFN) in 1,000-unit quantities.
Availability: available now
Data sheet? yes, see ISL6615 or ISL6615A
Note: the ISL6615 and ISL6615A are pin-for-pin compatible with Intersil’s previous generation ISL6594D.
