Finally the pinout for the chip (attached), and a list of things to measure:
1. battery voltage 3.3 - 4.2V
2. Pins of interest:
Name Pin Description Voltage(min/typ/max)
--------- ----- ---------------- --------------------------------
VIN 10 Input power supply to general circuitry. 3.0/3.7/6.0
VIN_P 24 Input power supply to inverting buck-boost converter (DCDC2). 3/3.7/6
VN_SW 25 Inverting buck-boost converter switch out (DCDC2). -16V
VN 26 Feedback pin for inverting buck-boost converter (DCDC2) and supply for VNEG LDO and VEE charge pump. 16v(?)
VB_SW 40 Boost converter switch out (DCDC1). 16V
PGND1 41 Power ground for DCDC1. 0V
VB 42 Feedback pin for boost converter (DCDC1) and supply for VPOS LDO and VDDH charge pump. 16V(?)
Simples...
