1-Cell, 1.5A Battery Charger PMIC with 20mA Termination, Ultra-Low IQ Reverse Boost, and I2C

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 1.5A 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.

Benefits

* Low IQ solution * High efficiency fast charging of up to 1.5A and PFM mode light loads of up to 20mA * Reverse boost up to 1A and PFM mode on light loads (60μA) * Low IQ linear chargers (LDOs) that can support up to 350mA * Single input to support USB input and high voltage adapters - Supports 4.0V to 10.0V input voltage * Ultra-low leakage state during shipmode * High accuracy battery charging profile ±5% charge current regulation * Dynamic power path balancing that reduces charging current and input current as necessary and allows VSYS to draw current from both supplies during peak loads * Programmable 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 inputs * Inbuilt die temperature monitoring and battery temperature monitoring
