The LT1511ISW#TRPBF is a current-mode PWM battery charger IC designed by Analog Devices for efficient charging of modern rechargeable batteries. It supports lithium-ion (Li-Ion), nickel-metal-hydride (NiMH), and nickel-cadmium (NiCd) chemistries, requiring constant-current and/or constant-voltage charging.
This IC features an internal switch capable of delivering 3A DC current and can charge batteries ranging from 1V to 20V. The charging current is programmable to within 5% accuracy, and it boasts a 0.5% reference voltage accuracy, crucial for Li-Ion cell charging. A third control loop regulates the current drawn from the AC adapter, allowing simultaneous equipment operation and battery charging without overloading the adapter.
The LT1511ISW#TRPBF operates with an input voltage range of 11V to 28V. It is housed in a 24-SOIC package and supports surface mount installation. The device includes over-voltage fault protection and operates within a temperature range of -40°C to 85°C.
Key features include high charging efficiency due to a 200kHz saturating switch, small inductor size, and low reverse battery drain current of 3μA when the adapter is unplugged. It offers adjustable undervoltage lockout and automatic shutdown when the AC adapter is removed.
