MAX1873REEE+, Зарядное устройство для 4-элементной литий-ионной батареи, 28В вход, 4A зарядка, QSOP-16 /Код si-883408

Полупроводники - Микросхемы\Микросхемы Управления Питанием\Управление Питанием Батарей\Микросхемы Зарядных УстройствThe MAX1873REEE+ is a simple current-limited switch mode Li+ charger controller in 16 pin QSOP package. It provides a regulated charging current and voltage with less than ±0.75% total voltage error at the battery terminals. An external P channel MOSFET operates in a step down DC-DC configuration to efficiently charge batteries in low cost designs. The MAX1873 device regulates the battery voltage and charging current using two control loops that work together to transition smoothly between voltage and current regulation. An additional control loop limits current drawn from the input source so that AC adapter size and cost can be minimized. An analogue voltage output proportional to charging current is also supplied so that an ADC or microcontroller can monitor charging current. This device is used as an efficient current limit source to charge NiCd or NiMH batteries in multi-chemistry charger designs. • Charges 2 lithium-ion cells or 5 or 6 Ni battery cells• Operating temperature range from -40°C to 85°C• Input voltage range from 6VDC to 28VDC, charging current is 4A• AC adapter input current limit loop• Analogue output monitors charge current• 5µA shutdown battery current• 200mV dropout voltage, 100% duty cycle• Adjustable charging current• 300KHz PWM oscillator reduces noise
