Its battery pack voltage range spans 2.4 V to 18.304 V, and the maximum supply voltage is 23.4 V, covering most portable and embedded multi-cell designs. Fault protection includes over-current, over-temperature, and over-voltage monitoring, which helps safeguard the pack and the charging circuit during abnormal conditions. ## Interface, programmability, and temperature range Communication with a host microcontroller runs over I²C, SMBus, or USB interfaces, allowing the charge current to be set programmatically through the bus. The operating temperature range is -10°C to 100°C ambient, which suits consumer and industrial equipment that stays above freezing but does not require full automotive grade. Packaged in a 32-WFQFN with exposed pad (also designated 32-TQFN 4x4 mm), the part is surface-mount and supplied on Tape & Reel for automated assembly.","metaTitle":"ISL9238HRTZ-TK Renesas Battery Charger, 1-4 Cell Li-Ion","metaDescription":"ISL9238HRTZ-TK Renesas battery charger IC for 1-4 cell Li-Ion/Polymer packs.
