PRODUCTION DATA
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NUMBER | ||
P2 | 1 | O | LED 2 or Not Used (connect to Vss) |
VEN | 2 | O | Active High Voltage Translation Enable. This signal is optionally used to switch the input voltage divider on/off to reduce the power consumption (typ 45 µA) of the divider network. If not used, then this pin can be left floating or tied to Vss. |
P1 | 3 | O | LED 1 or Not Used (connect to Vss). This pin is also used to drive an LED for single-LED mode. Use a small signal N-FET (Q1) in series with the LED as shown on Figure 8-4. |
BAT | 4 | I | Translated Battery Voltage Input |
CE | 5 | I | Chip Enable. Internal LDO is disconnected from REGIN when driven low. |
REGIN | 6 | P | Internal integrated LDO input. Decouple with a 0.1-µF ceramic capacitor to Vss. |
REG25 | 7 | P | 2.5-V Output voltage of the internal integrated LDO. Decouple with 1-µF ceramic capacitor to Vss. |
VSS | 8 | P | Device ground |
SRP | 9 | I | Analog input pin connected to the internal coulomb-counter peripheral for integrating a small voltage between SRP and SRN where SRP is nearest the BAT– connection. |
SRN | 10 | I | Analog input pin connected to the internal coulomb-counter peripheral for integrating a small voltage between SRP and SRN where SRN is nearest the PACK– connection. |
P6/TS | 11 | I | Pack thermistor voltage sense (use 103AT-type thermistor) |
P5/HDQ | 12 | I/O | Open drain HDQ Serial communication line (slave). If not used, then this pin can be left floating or tied to Vss. |
P4/SCL | 13 | I | Slave I2C serial communication clock input. Use with a 10-KΩ pull-up resistor (typical). This pin is also used for LED 4 in the four-LED mode. If not used, then this pin can be left floating or tied to Vss. |
P3/SDA | 14 | I/O | Open drain slave I2C serial communication data line. Use with a 10-kΩ pull-up resistor (typical). This pin is also used for LED 3 in the four-LED mode. If not used, then this pin can be left floating or tied to Vss. |
