ML9078-001

LSI for power-saving solar power supply control

Outline

ML9078-001 is power supply control LSI which performs selection control for a solar cell power supply and a primary

battery. This LSI consists of a direct switch circuit and a regulator circuit, and each circuit performs the following

operations.

●

Direct switch circuit

Primary battery side direct switch circuit (BAT_DIRECT)

This always compare the primary battery side voltage (V_BAT) with the output voltage (VDO) of

ML9078-001. In case V_BAT>VDO, a primary battery side direct switch will be set to ON and the primary

battery side voltage (V_BAT) is supplied to the output voltage (VDO).

Solar cell side direct switch circuit (SC_DIRECT)

This always compare the solar cell side voltage (V_SC) with the output voltage (VDO) of ML9078-001. In

case V_SC>VDO, a solar cell side direct switch will be set to ON and the primary battery side voltage (V_SC)

is supplied to the output voltage (VDO).

●

Regulator circuit

The solar cell side voltage (Vsc) will be limited to be 1.65V(typ) or 3.3V(typ).

Feature

●

Comparison of primary battery power supply voltage (V_BAT) and solar cell power supply voltage (V_SC) is performed,

and the power supply source is selected automatically.

When primary battery voltage (V_BAT) is higher than solar cell voltage (V_SC), it outputs primary battery voltage

(V_BAT) to the output terminal (VDO) of ML9078-001.

When solar cell voltage (V_SC) is higher than primary battery voltage (V_BAT), it outputs solar cell voltage (V_SC) to

the output terminal (VDO) of ML9078-001.

●

The adverse current from a solar cell to a primary battery is prevented.

When primary battery voltage is low, the direct switch by the side of a primary battery turns off. The adverse

current to a primary battery from a solar cell is prevented, and the primary battery destruction by the adverse

current from a solar cell to a primary battery can be prevented.

●

Direct power supply from whether a solar cell output or a primary battery output to the external LSI is available. (at

the time of SCREG=L)

The regulator output voltage is selectable by the external input.

(at the time of SCREG=H)

In case SCLV=L : regulator output voltage(V_LD) will be limited to be 1.65V(typ) (V_SC>=2V, I_SC<=0.1mA, 25 °C

conditions)

In case SCLV=H : regulator output voltage(V_LD) will be limited to be 3.3V(typ) (V_SC>=3.6V, I_SC<=0.8mA, 25 °C

conditions)

●

Low power operation

Primary-battery side consumption current: Max 80nA at 25°C

SCREG=L,SCLV=X,Solar-cell side consumption current: Max 80nA at 25°C

SCREG=H,SCLV=L,Solar-cell side consumption current: Max 250nA at 25°C

SCREG=H,SCLV=H,Solar-cell side consumption current: Max 1200 nA at 25°C

A monitor of the use situation of a solar panel is possible.

In case DI_MONI=H, current is supplied from solar cell to external circuit.

In case DI_MONI=L, current is supplied from primary battery to external circuit.
