Short-Form Datasheet  
ISL99360, ISL99360B  
Smart Power Stage (SPS) with Integrated High Accuracy Current and  
Temperature Monitors  
The ISL99360 and ISL99360B are Smart Power  
Stages (SPS) compatible with the ISL68xxx/69xxx  
Features  
• Input range: +3.0V to +16V  
Digital Multiphase (DMP) controllers and phase  
doubler (ISL6617A), respectively. The ISL99360 and  
ISL99360B have integrated high accuracy current and  
temperature monitors that can be fed back to the  
controller and doubler to complete a multiphase  
DC/DC system. They simplify design and increase  
performance by eliminating the DCR sensing network  
and associated thermal compensation. Light-load  
efficiency is supported through a dedicated LFET  
control pin. An industry leading thermally enhanced  
5x5 PQFN package allows minimal overall PCB real  
estate.  
• Supports 60A DC current  
• ISL99360: 3.3V compatible tri-state PWM input  
• ISL99360B: 5.0V compatible tri-state PWM input  
• Downslope current sensing  
• ±3% accuracy current monitor (IMON) with REFIN  
input  
• 8mV/°C temperature monitor with OT flag  
• Dedicated low-side FET control input  
• Comprehensive fault protection for high system  
reliability  
The ISL99360 and ISL99360B feature a 3.3V  
compatible, 5.0V compatible tri-state PWM input that  
works together with the Renesas multiphase PWM  
controllers to provide a robust solution in abnormal  
operating conditions. The ISL99360 and ISL99360B  
also improve system performance and reliability with  
integrated fault protection of UVLO, HFET short,  
over-temperature, and overcurrent. An open-drain  
fault reporting pin simplifies the handshake between  
the SPS and controllers and can disable the controller  
during start-up and fault conditions.
