SLVS658B – MARCH 2006 – REVISED FEBRUARY 2007

NAME PIN I/O DESCRIPTION EXTERNAL REQUIRED COMPONENTS

(SEE APPLICATION DIAGRAM)

TMR 13 I Charge safety timer program input External resistor from TMR pin to AGND1 pin sets the charge

safety timer time-out value

TRSTPWON 20 I System reset pulse-duration setting 100-nF (minimum) capacitor to AGND. External capacitor from

TRSTPWON pin to AGND1 pin sets RESPWRON pulse

duration.

TS 12 I/O Temperature sense input, current source Connect to battery pack thermistor to sense battery pack

output temperature. Connect to external pullup resistor.

USB 6 I USB charge input voltage, connect to 1- µ F (minimum) capacitor to AGND1 pin, to minimize

USB port positive power output overvoltage transients during USB power hot-plug events.

VIN_LDO35 29 – Input to LDOs 3 to 5 1- µ F (minimum) decoupling capacitor to AGND2

VIN_LDO02 35 – Positive supply input for LDO0, LDO1, 1- µ F (minimum) decoupling capacitor to AGND1

LDO2

VIN_SM1 47 – SM1 synchronous buck converter positive 10- µ F capacitor to PGND1 pin

supply input

VIN_SM2 50 – SM2 synchronous buck converter positive 10- µ F capacitor to PGND2 pin

supply input

Exposed 57 – There is an internal electrical connection between the exposed thermal pad and AGNDn pins of the IC. The

thermal pad exposed thermal pad must be connected to the same potential as the AGND1 pin on the printed circuit

board. Do not use the thermal pad as the primary ground input for the IC. AGNDn pins must be connected

to a clean ground plane at all times.
