Announcement: Introducing HL8545/G: Quad-Channel 50 mΩ High-Side Switch for Advanced Automotive Applications

Overview

HL7095 is a fully integrated switch-mode Li-ion battery chargers with power FETs, power path management, I²C interface, reverse boost function. It can be used with single cell or multiple-cell in parallel Li-ion and Li-polymer batteries in a wide range of wearable devices, smart phones, tablets, power banks and other portable devices. Its switch-mode operation and low-resistance power path maximize charging, discharging and boost efficiency, reduce battery charging time and extend battery life during the discharging phase.

This device supports a wide range of input sources, including standard USB host port, USB charging port and AC-DC adapter. It supports an input operating voltage from 4V to 12V and can power up the system rail without a battery. It can automatically adjust to the maximum power output of the input source via the input dynamic power management control (INDPM).

HL7095 integrates comprehensive protections mechanism to ensure safe operation of the battery, including battery temperature monitoring via negative temperature coefficient (NTC) thermistor, charging safety timer, over-voltage and under-voltage detection. The device also provides output over-current protection and regulates its on-chip junction temperature (TJ_REG) to be no more than thermal regulation threshold by regulating its charging current.

HL7095 is available in a 2.17mm x 2.57mm 30 balls WLCSP package.
