Yu-tai ETA9687 Observing IC power shift operation

Integrated interface identification, without D + D- resistance, omnipotent filling a chip meets all functional mobile power, a cleaner look, less BOM cost, greatly improve the production efficiency integrated power display and all dependent the MCU to achieve functional without lithium protection IC and MOSFET and any other active devices, which greatly simplifies the design of mobile power output short program does not lock problem DW01 discharge 1A, 2.1A boost efficiency of 90%, small to 2.2uH inductance 5V /2.1A synchronous boost efficiency up to 90%, 2MHz switching frequency, inductor small, the output ripple small-load standby power consumption less than 150uA 1A linear charging, and with input overvoltage protection original single LED, "heartbeat light "LED display power, battery indicator energy consumption reduced by 80% overcharge, over discharge, output short circuit protection, short-circuit self-recovery, charging the input circuit protection Xiangxi more information, please contact Miss Long: 18565879459
