Title:
LOAD CONTROLLER
Document Type and Number:
Japanese Patent JP2009017180
Kind Code:
A
Abstract:
To provide a load controller capable of detecting short circuiting of a load, without requiring a complex circuit configuration.
According to a pulse-shaped short circuit detection cancel signal, a transistor Q1 is forcedly turned on for a fixed period and a transistor Tr1 for applying current to a load 30 is turned on. This load controller comprises a short-circuit detecting circuit 21 for detecting short circuits, based on the potential arising at a connection point A, in accordance with a state whether the load 30 is short-circuited.
