Description
Two logic inputs (active-low EN1, active-low EN2) select suspend mode, 100mA, 500mA, or ≤ 1A input current limits to comply with USB requirements. Proprietary thermal-regulation circuitry limits the die temperature to +100°C to prevent excessive heat on the system PC board. Additional safety features include an NTC thermistor input (THM) to protect the battery. A 3.5V to 4.2V SYS output, in conjunction with the low-RDSON battery switch, powers the system even when the battery is deeply discharged or not installed. The IC also offers a +3.3V/500µA output (VL), a charging status flag (active-low CHG), and an input-supply detection flag (active-low POK). The MAX8856 operates from a +4.25V to +5.5V supply and includes undervoltage lockout below +3.4V and overvoltage protection up to +14V.
