  • Publication number: 20240079897
    Abstract: A circuit device includes: a current source circuit; a first charging circuit; a second charging circuit; and a control circuit. The control circuit controls, when a current setting value is in a first current range, supply of a first charging current from the first charging circuit to a charging node. The control circuit controls, when the current setting value is in a second current range on a current side higher than the first current range, supply of a second charging current from the second charging circuit to the charging node. The control circuit sets the current source control value such that the output current of the current source circuit is zero or is reduced during a switching period of the current source control value.

  • Publication number: 20240079898
    Abstract: A circuit device includes: a current source circuit; a first charging circuit; a second charging circuit; and a control circuit. The control circuit controls, when a current setting value is in a first current range, supply of a first charging current from the first charging circuit to a charging node. The control circuit controls, when the current setting value is in a second current range on a current side higher than the first current range, supply of a second charging current from the second charging circuit to the charging node. The control circuit sets both the first charging current and the second charging current to a non-supply state during a switching period between the first current mode and the second current mode.

  • Publication number: 20240047987
    Abstract: A circuit device includes a current source circuit, a first charging circuit, a second charging circuit, and a control circuit. The control circuit supplies, when a current setting value is in a first current range, a first charging current of a current value indicated by a first setting value from the first charging circuit to a charging node. The control circuit supplies, when the current setting value is in a second current range, a second charging current of a current value indicated by a second setting value from the second charging circuit to the charging node. The control circuit performs at least one of first correction for correcting a first conversion characteristic and second correction for correcting a second conversion characteristic.

  • Publication number: 20230268757
    Abstract: A circuit device includes a current source circuit, a first charging circuit, a second charging circuit, and a control circuit. The first charging circuit supplies a first charging current as a constant current based on an output current of the current source circuit. The second charging circuit supplies a second charging current which is a constant current and is higher than the first charging current based on the output current of the current source circuit. The control circuit makes the first charging circuit supply the first charging current when a current value of the charging current is determined as a current value in the first current mode. The control circuit makes the second charging circuit supply the second charging current when the current value of the charging current is determined as a current value in the second current mode higher than the current value in the first current mode.
