SGM4056

High Input Voltage Charger

GENERAL DESCRIPTION

FEATURES

The SGM4056 is a cost-effective, fully integrated high

input voltage single-cell Li-Ion battery charger. The

charger uses a CC/CV charge profile required by Li-Ion

battery. The charger accepts an input voltage up to

26.5V but is disabled when the input voltage exceeds

the OVP threshold, typically 6.8V (SGM4056-6.8) or

10.5V (SGM4056-10.5), to prevent excessive power

dissipation. The 26.5V rating eliminates the over-

voltage protection circuit required in a low input voltage

charger.

● Complete Charger for Single-Cell Li-Ion or

Polymer Batteries

● Integrated Pass Element and Current Sensor

● No External Blocking Diode Required

● Low Component Count and Cost

● Programmable Charge Current

● Programmable End-of-Charge Current

● Charge Current Thermal Foldback for Thermal

Protection

● 2.55V Trickle Charge Threshold

● 6.8V Input Over-Voltage Protection

for SGM4056-6.8

The charge current and the end-of-charge (EOC)

current are programmable with external resistors.

When the battery voltage is lower than typically 2.55V,

the charger preconditions the battery with typically 18%

of the programmed charge current. When the charge

current reduces to the programmable EOC current level

during the CV charge phase, an EOC indication is

provided by the CHG pin, which is an open-drain

output. An internal thermal foldback function protects

the charger from any thermal failure.

● 10.5V Input Over-Voltage Protection

for SGM4056-10.5

● 26.5V Maximum Voltage for the Power Input

● Power Presence and Charge Indications

● Less than 1μA Leakage Current off the Battery

When No Input Power Attached or Charger

Disabled

● Available in Green TDFN-3×3-8L, TDFN-2×3-8L,

TDFN-2×2-8L and SOIC-8 (Exposed Pad) Packages

Two indication pins (

and CHG ) allow simple

PPR

interface to a microprocessor or LEDs. When no

adapter is attached or when disabled, the charger

draws less than 1μA leakage current from the battery.
