Overview

2.1

Power supply: VCC

The supply voltage VCC (3.3 V / 5 V) supplies the whole device. In case of power-on (VCC

increases from undervoltage to VPOR OFF = 2.75 V, typical) the circuit is initialized by an

internally generated power-on reset (POR). If the voltage VCC decreases under the

minimum threshold (VPOR ON = 2.55 V, typical), the outputs are switched off in 3-state (high

impedance). The status registers are cleared and the control registers are reset to their

default.

2.2

Power supply: VSA, VSB

Each VSA and VSB supplies the half bridges independently.

VSA → Out 1 to Out 3

VSB → Out 4 to Out 6

2.3

Standby mode

The standby mode of the L99MD02 is activated by EN pin to low. The inputs and outputs are

switched off. The status registers are cleared and the control registers are reset to their

default values.

In the standby mode the current consumption is typically 5 µA.
