MP2617BGL-Z

MONOLITHIC POWER SYSTEMS · Global Sourcing Parts · QFN-20(3x4)

MP2617BGL-Z from MONOLITHIC POWER SYSTEMS, in a QFN-20(3x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BST passive Bootstrap pin; a capacitor between SW and BST forms a floating supply for the power switch gate driver (BST rated -0.3V to +26V).
2 SW power_out Switch output of the synchronous buck regulator (rated -0.3V to +20V).
3 IN power_in Power input of the IC from adapter or USB; operating range 4.0V to 10V, rated -0.3V to +20V.
4 SW power_out Switch output of the synchronous buck regulator (rated -0.3V to +20V).
5 PGND power_in Power ground.
6 EN input Active-low logic enable: logic low enables the part and logic high disables it (low <0.4V, high >1.5V).
7 M0 input Mode select input that, combined with M1, sets the input current limit mode (logic high 1.5V min, low 0.4V max).
8 M1 input Mode select input that, combined with M0, sets the input current limit mode (logic high 1.5V min, low 0.4V max).
9 CHGOK output Open-drain output pulled low during charging and pulled high through an external resistor to VCC when charge is complete (low voltage 270mV typ at 5mA sink).
10 ACOK output Open-drain output pulled low to indicate a valid input supply, otherwise pulled high through an external resistor to VCC (low voltage 270mV typ at 5mA sink).
11 AGND power_in Analog ground.
12 SYSFB input SYS voltage program pin; connect a resistor divider from SYS to AGND to program the system output voltage, or leave floating to disable the function.
13 SYS power_out DC-DC regulator output that powers the system load and charges the battery (rated -0.3V to +6V).
14 BATT bidirectional Positive battery terminal (rated -0.3V to +6V); MP2617B terminal charge voltage is 4.2V typ.
15 ISET passive Charge current program pin; a resistor to AGND sets the CC charge current (e.g. 1.53k gives 1.4A typ), and floating the pin disables charging.
16 NTC input Thermistor input; connect a resistor from this pin to VCC and the thermistor (usually in the battery pack) from this pin to ground.
17 ILIM passive Input current limit program pin; a resistor to AGND sets the input current limit with adapter input.
18 TMR passive Sets the charge timer period with a capacitor; connect TMR to AGND to disable the internal timer.
19 VLIM passive Input voltage clamp program pin.
20 VCC power_out Supply voltage of the IC, with 4.5V typ output voltage and 40mA typ output current limit.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
