• Manufacturer Part Number: 71m6521be
• Description: Energy Meter Ic
• Manufacturer: Maxim Integrated Products, Inc.

SUPPLY CURRENT
†
V3P3D SWITCH
2.5V VOLTAGE REGULATOR
Unless otherwise specified, load = 5mA
Page: 86 of 97
Current into V3P3A and V3P3SYS pins is not zero if voltage is applied at these pins in brownout, LCD or sleep modes.
PARAMETER
V3P3A + V3P3SYS current
VBAT current
V3P3A + V3P3SYS current vs.
MPU clock frequency
V3P3A + V3P3SYS current,
Write Flash
VBAT current
PARAMETER
On resistance – V3P3SYS to V3P3D
On resistance – VBAT to V3P3D
PARAMETER
Voltage overhead V3P3-V2P5
PSSR ΔV2P5/ΔV3P3
Normal Operation,
V3P3A=V3P3SYS=3.3V
MPU_DIV = 3 (614kHz), CKOUT_E =
0, CE_EN = 1, RTM_E = 0, ECK_DIS =
1, ADC_E = 1, ICE_E = 0
Same conditions as above
Normal Operation as above, except
write Flash at maximum rate, CE_E=0,
ADC_E=0
VBAT=3.6V
BROWNOUT mode, <25°C
BROWNOUT mode, >25°C
LCD Mode, 25°C
LCD mode, over temperature
SLEEP Mode, 25°C
Sleep mode, over temperature
