The Renesas Electronics ISL9241HRTZ-TK is a highly versatile buck-boost charger designed for 2-, 3-, or 4-cell Li-ion battery applications, making it ideal for modern portable devices and smart systems. Featuring advanced NVDC (narrow voltage DC) or hybrid power (turbo boost) charging modes, it uses all NFET transistors to optimize efficiency and performance. With an input voltage range of 3.9V to 23.4V and a system/battery output voltage of 3.9V to 18.304V, it provides wide compatibility and excellent flexibility in power delivery designs. The IC supports bypass mode to directly connect the system to an adapter and includes features like autonomous charging, adapter and battery current monitoring, and open-drain output for PROCHOT#, ensuring seamless operation and protection under varying conditions.
Designed to meet the high standards of next-generation power management, the ISL9241HRTZ-TK offers USB-C PD Fast Role Swap and PPS support, along with battery ship mode for ultra-low power consumption. Additional features include an 8-bit internal ADC for monitoring critical parameters, JEITA compliance support, and PSYS output for system power monitoring in IMVP8/9-compliant designs. With its compact 4x4 TQFN package, this charger is perfect for space-constrained applications while offering advanced functionality for forward and reverse operation modes.
