uP9650AQR1 marking uP9650a Powering Chip for Iceriver KS0 Pro Hashboard

Product description:

uP9650AQR1 is a powering chip located on the IceRiver KS0 PRO board with fully optimized integrated drivers and MOSFETs for high-current, high-frequency, synchronous step-down DC-DC converters. It is packed with VQFN6x5-39L, and supports advanced high-precision module temperature reporting and on-chip synchronous MOSFET current monitoring, with features including cycle-by-cycle overcurrent protection, phase fault detection, preliminary overvoltage protection, VCC/VDRV UVLO protection, and thermal shutdown.

Product feature:

• Input voltage from 4.5V to 22V
• 4.5V to 5.5V for VCC and VDRV supply voltages
• Up to 60A current handling capability
• Optimized switching frequency up to 1MHz
• 5mV/A on-chip MOSFET current sensing
• 8mV/oC temperature analog output
• On-chip MOSFET temperature compensation
• VCC/VDRV Undervoltage Lockout (UVLO)
• Thermal shutdown and fault flags
• MOSFET phase fault detection and flagging
• Cycle-by-cycle overcurrent protection
• Preliminary overvoltage (OV) protection and flagging
• Compatible with 3.3V and 5V tri-state PWM inputs
