ISL99392R5935, ISL99392BR5935
90A Smart Power Stage (SPS) Module with Integrated High Accuracy Current and Master or Individual
Temperature Monitors
The ISL99392R5935 and ISL99392BR5935 are 90A
Smart Power Stages (SPS) that are compatible with
Renesas ISL68/69xxx Digital Multiphase (DMP)
controllers and phase doublers (ISL6617A),
Features
• V input range: +3.0V to +16V
IN
• Supports 90A DC current
respectively. The ISL99392R5935 and
• 3.3V compatible tri-state PWM input
(ISL99392R5935)
ISL99392BR5935 offer best-in-class current sense
accuracy over line, load, and temperature. When
combined with a Renesas digital PWM controller (or
doubler), these devices enable precision system level
power management and best-in-class transient
response for load-line based regulators. In addition to
the common master TOUT signal to the DMP, the
individual phase Temperature Reporting (TREF)
supports thermal management and N+1 redundancy
system management. The ISL99392R5935 and
ISL99392BR5935 simplify design by eliminating
typical DCR sensing networks and associated thermal
compensation components. The thermally enhanced
5x6 package enables high density designs.
• 5V compatible tri-state PWM input
(ISL99392BR5935)
• ±3% accuracy continuous signal for current monitor
• 8mV/°C master temperature monitor, TOUT
• 4mV/°C individual temperature monitor, TREF
• Comprehensive fault protection for high system
reliability
○ High-side FET short and overcurrent protection
○ Smart Reverse Overcurrent Protection (SROCP)
○ Over-Temperature Protection (OTP)
The ISL99392R5935 features the Renesas tri-state
PWM input that works with the Renesas
○ V Undervoltage Lockout (UVLO)
CC
• Fault reporting outputs
ISL682xx/ISL692xx digital multiphase PWM
controllers to provide a robust solution in event of
abnormal operating conditions. The ISL99392R5935
and ISL99392BR5935 also improve system
performance and reliability with integrated fault
protection, including HFET overcurrent, HFET
shorted, Smart Reverse Overcurrent (SROCP),
• Up to 1.25MHz switching frequency
• RoHS compliant with Exemption 7a, 5x6 PQFN
Applications
• Accelerators (GPU, ASIC, artificial intelligence)
• Core, graphic, and memory VRs for microprocessors
Over-Temperature (OTP), and V Undervoltage
CC
Lockout (UVLO).
• High density VR for server, networking, and cloud
computing
• POL DC/DC converters and video gaming consoles
