Qualcomm (Summit) Battery Charging IC Solution SMB348 (1.5A) / 358 (2A)

Like all Qualcomm (Summit) battery charging IC solutions, the SMB348/358 chip has the same high integration and high flexibility design capabilities. Digital I2C control and non-volatile configuration while maintaining the simplicity of independent operation or the flexibility of host control. Parameters and functions can be easily reconfigured to suit a variety of applications or system operating modes. High integration and high frequency operation reduce external use parts, and the CSP package also helps with smaller solution sizes.

The SMB348/358 is the ideal charging and system power solution for virtually any portable product that uses high-capacity batteries and requires reliable fast charging.

Introduction:

The SMB348 and SMB358 are programmable charging ICs that can be used in single Lithium-ion/Lithium-polymer battery charging designs, making them ideal for a wide range of portable applications. This IC provides a simple and efficient way to charge high-capacity Li-Ion batteries and provide system power through the input power of a USB or AC transformer. The SMB348 and SMB358's high-efficiency switching modes operate differently than traditional linear charging ICs, solving the problem of low charging current and heat. In addition, its programmable switching architecture avoids USB input current limitations and provides faster charging.

USB and AC input current limits up to 2.0A and charge currents up to 2.0A (SMB358) and 1.5A (SMB348). These products can manage two independent outputs: battery charging and system power. This allows the system to start up immediately even when there is no battery or the battery is over-discharged. The internal hardware design of the SMB348 and SMB358 is also available with a +5.0 V/900mA power supply for external USB OTG devices via the battery, as well as USB-ACA standards.

Charging control includes input current limit (supports USB2.0 and USB3.0), slow charging, pre-charging, constant current/constant voltage charging, floating charging and termination/safety settings all pass through I2C/SMBus It is set up and stored in the non-volatile memory in the IC, which truly realizes a flexible and flexible solution. The size of the fast charge current can be set via I2C. An external enable pin is also provided to set the charge to suspend or put it into sleep mode and built-in reverse current blocking to prevent accidental battery discharge.

These two products offer a variety of protection features such as battery, charger, input circuit (overcurrent, low voltage / over voltage, safety timer, floating charging voltage and charging current, floating charging voltage compensation and thermal protection) . The “STAT” pin can also be used to monitor the state of charge. The operating voltage is +3.6V to +6.2 V and provides overvoltage protection of +20 V.
