Level 2 Smart Battery Charger
Pin Description
PIN
NAME
FUNCTION
1
IOUT
Linear Current-Source Output
2
DCIN
Input Voltage for Powering Charger
3
VL
IC Power Supply. 5.4V linear-regulator output from DCIN.
4
CCV
Voltage-Regulation-Loop Compensation Point
5
CCI
Current-Regulation-Loop Compensation Point
6
SEL
Current-Range Selector. Connecting SEL to VL sets a 4A full-scale current. Leaving SEL
open sets a 3A full-scale current. Connecting SEL to AGND sets a 1A full-scale current.
7
CS
Current-Sense Positive Input
8
BATT
Battery Voltage Input and Current-Sense Negative Input
9
REF
+4.096V Reference Voltage Output or External Reference Input
10
AGND
Analog Ground
11
INT
Open-Drain Interrupt Output
12
THM
Thermistor Sense Voltage Input
13
SCL
Serial Clock (need external pull-up resistor)
14
SDA
Serial Data (need external pull-up resistor)
15
DACV
Voltage DAC Output Filtering Point
16
PGND
Power Ground
17
DLO
Low-Side Power MOSFET Driver Output
18
DHI
High-Side Power MOSFET Driver Output
19
LX
Power Connection for the High-Side Power MOSFET Driver
20
BST
Power Connection for the High-Side Power MOSFET Driver
