Dual-Input Linear Charger, Smart Power Selector

with Advanced Battery Temperature Monitoring

General Description

Features

Li+ Charger with Smart Power Selector, No

The MAX8934G dual-input Li+/Li-Poly linear battery char-

ger with Smart Power SelectorK safely charges a single

Li+/Li-Poly cell in accordance with JEITA* recommenda-

tions. The MAX8934G monitors the battery temperature

) while charging, and automatically adjusts the

fast-charge current and charge termination voltage as the

battery temperature varies. The MAX8934G also monitors

the battery temperature while the battery is discharging,

and provides a warning flag (OT) to the system in the

event that the battery is over temperature. Safety region

Supported by Battery

2 is supported (see Figure 6 for details). An ultra-low I ,

always-on LDO provides an additional 3.3V supply for

system power.

The MAX8934G operates with either separate inputs

for USB and AC adapter power, or from a single input

that accepts both. All power switches for charging and

switching the load between battery and external power

are included on-chip. No external MOSFETs are required.

40mI SYS-to-BATT Switch

Thermal Regulation Prevents Overheating

4.35V SYS Regulation Voltage

The MAX8934G features a Smart Power Selector to make

the best use of limited USB or adapter power. Input cur-

rent limit and battery charge current limit are indepen-

dently set. Input power not used by the system charges

the battery. Charge current limit and DC current limit can

be set up to 1.5A and 2A, respectively, while USB input

current can be set to 100mA or 500mA. Automatic input

selection switches the system load from battery to external

power.

**EP = Exposed pad.

The MAX8934G provides a SYS output voltage of 4.35V.

Typical Operating Circuit

Other features include overvoltage protection (OVP),

open-drain charge status and fault outputs, power-OK

monitors, charge timers, and a battery thermistor moni-

tor. Additionally, on-chip thermal limiting reduces the

battery charge-rate to prevent charger overheating.

The MAX8934G is available in a 28-pin, 4mm x 4mm,
