Within a cooling fan control IC
1, the resistance partial pressure circuit is to get basic level when the modulus conversion, the two resistance has a problem, can cause the entire migration speed curve.
2, used in the current LIMIT, LIMIT feet protect MOS driver IC, when MOS driver IC output large current LIMIT feet a character to the measurement signal, programmable IC immediately cut off peak current, thus protecting the MOS driver IC. Wenling city tong chi auto air conditioning manufacturing co. , LTD. , specializing in the production of cooling fans.
