Diodes Inc. AP9234L, Now at Mouser, Puts High-Accuracy Li+ Protection on Single Chip

December, 2015 – Mouser Electronics, Inc. is now stocking the new AP9234L battery protection IC from Diodes Incorporated. This single-chip protection solution provides a rich set of protection features for single-cell lithium-ion or lithium-polymer rechargeable battery packs in smartphones, cameras, and other electronic equipment.

The Diodes Inc. AP9234L battery protection IC, now available at Mouser Electronics, integrates a high-accuracy battery protection circuit with a dual N-channel, common-drain MOSFET that features an ultra-low R_SS(ON) specification, typically just 13 mOhms (at V_DD = 4.0V, I_D = 1.0A). The AP9234L device safely charges and disgorges the battery by turning the MOSFET off when overcharge voltage/current, over-discharge voltage/current, or load short-circuit conditions are detected. The circuit also includes a built-in fixed, delay time to protect external components. The device delivers power savings through a low quiescent current, typically 3.0μA in normal mode and 0.1μA in power-down mode. Additionally, an over-current detection voltage compensation circuit assures current limit accuracy. The AP9234L features power-down capability, as well as a selectable auto-wake-up function, and offers protection voltage customization for different cell-type specifications.

The AP9234L is available in a UDFN2535-6 surface-mount package and capitalizes on a high-voltage CMOS process to withstand extreme transient and surge voltages from adapters. With an integrated compensation circuit, it can ensure highly accurate charge/discharge current limit range in the full operating temperature range of ‑40 to +85 degrees Celsius.
