» Max1873reee T Maxim Simple Current Controller, 30v, 50ma, 667mw, Qsop
Product Description:
Part Number: MAX1873REEE+T Maxim simple current-limited switch-mode Li charger controller, 30V, 50mA,
667mW, QSOP-16
Description:
Product Summary
The MAX1873REEE+T is a simple current-limited switch-mode Li charger controller. The MAX1873REEE+T provides all functions needed to simply and efficiently charge 2-, 3-, or 4- series lithium-ion cells at up to 4A or more. The MAX1873REEE+T 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 MAX1873REEE+T 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 analog voltage output proportional to charging current is also supplied so that an ADC or microcontroller can monitor charging current.
Parametrics
MAX1873REEE+T absolute maximum ratings: (1)CSSP, CSSN, DCIN to GND: -0.3V to +30V; (2)VL, ICHG/EN to GND: -0.3V to +6V; (3)VH, EXT to DCIN: -6V to +0.3V; (4)VH, EXT to GND : (VDCIN + 0.3V)to -0.3V; (5)EXT to VH : +6V to -0.3V; (6)DCIN to VL: +30V to -0.3V; (7)VADJ, REF, CCI, CCV, CCS, ; (8)IOUT to GND: -0.3V to (VL + 0.3V); (9)BATT, CSB to GND: -0.3V to +20V; (10)CSSP to CSSN: -0.3V to +0.6V; (11)CSB to BATT: -0.3V to +0.6V; (12)VL Source Current : +50mA; (13)VH Sink Current : +40mA; (14)Continuous Power Dissipation (TA = +70℃)16-Pin QSOP (derate 8.3mW/℃ above +70℃: +667mW; (15)Operating Temperature Range: -40℃ to +85℃; (16)Junction Temperature: +150℃; (17)Storage Temperature Range : -65℃ to +150℃; (18)Lead Temperature (soldering, 10s): +300℃.
