描述 Description

The DA9168 is a configurable Battery Management IC (BMIC) with integrated dual LDOs and reverse boost to support USB On-The-Go (USB-OTG). The extremely low quiescent current consumption in a very compact footprint makes it ideally suited for a multitude of space-conscious, battery-powered consumer applications. The fast-growing hearable segment for True Wireless Stereo (TWS), wearable segment for smartwatches, and a range of smart home applications such as smart cameras are examples where the DA9168 is an extremely good fit.

The device comprises a high-efficiency switch-mode charger with power path management capable of supporting up to 2A of charge current, dual LDOs that can be configured as load switches, and high-efficiency reverse boost functionality.

DA9168 has several power-saving modes to increase battery life whether the product sits on the shelf or is in operation. Further savings in power are achieved with the ultra-low IQ reverse boost converter that is efficient down to 60μA load currents with low power LDOs.

BenefitsLow IQ solutionHigh efficiency fast charging of up to 2A and PFM mode light loads of up to 20mAReverse boost up to 1A and PFM mode on light loads (60μA)Low IQ linear chargers (LDOs) that can support up to 350mASingle input to support USB input and high voltage adapters - Supports 4.0V to 10.0V input voltageUltra-low leakage state during shipmodeHigh accuracy battery charging profile ±5% charge current regulationDynamic power path balancing that reduces charging current and input current as necessary and allows VSYS to draw current from both supplies during peak loadsProgrammable OVP that can be used for a variety of charger applications such as wireless charging (up to 10V), wired (~6V), etc.OV, UV protection on VBAT and VSYS inputsInbuilt die temperature monitoring and battery temperature monitoring
