Congratulations on hycon's entry into Huawei's supply chain

After Guoju announced the acquisition of KEMET, an American passive component factory, on the 12th, it officially entered Huawei's supply chain at a cost of US $1.8 billion. Of course, it is not all for Huawei's sake, but it is also a big reason Hycon focuses on the production of lithium-ion battery protection cells. In this field, hycon has gradually become the leader in China. Its quality is on the same level with Seiko and Ricoh in Japan. It is recognized by the industry. This time, HY2143, a secondary protection chip of hycon, is chosen by Huawei as a WEATHERVANE, from sample to small batch, After a year of repeated testing and aging, hycon's quality can stand the test, and now it has been officially shipped in batches HY2143 is a secondary protection chip which can be used for 2, 3 and 4 strings. It is expected that it will be well known and popularized in the near future Product features Built in high precision battery current detection The delay time is set by the internal circuit (no external capacitor is required) Output logic: CMOS output, high level valid; High level output 4.7V (typical value) from voltage regulator Maximum effective time of output logic high level: optional, not limited to the default value Low current The typical value of working mode is 5.0 & mu; A. The maximum is 9.0 & mu; A（VCelln = 3.9V）。 Off mode 1: typical value 4.5 & mu; A. The maximum value is 8.0 & mu; A（VCelln = 3.1V）。 Off mode 2: typical value 0.6 & mu; A. Maximum 1.0 & mu; A（VCelln = 2.0V）。 LDO output circuit LDO output voltage is 3.0v/3.3v (typical value). Precision: & plusmn; 65mV The maximum output current of LDO is 2mA Input voltage detection level: The voltage detection level (from VDD) is 2.8V (typical value). Precision: & plusmn; 1V High voltage design: the absolute maximum rating is 30V Wide working temperature range: - 40 & deg; C to + 85 & deg; C Small package: dfn-2.0 * 2.0-8l Halogen free green products

Yingjixin ip2726: the first qc4 + certificate issued by Qualcomm!

As a leader in chip solutions for accessories, yingjixin technology has broken the situation that qc4.0/qc4.0 + chips are only licensed by European and American manufacturers and Taiwan manufacturers. It has become the first domestic manufacturer to obtain qc4.0 / qc4.0 + certification license from Qualcomm, with the certificate number of qc2019041666. According to the charging head network, yingjixin ip2726 is the first qc4 + certificate issued by Qualcomm Designed for the latest fast charging technology, the Intel Chipset ip2726 can support up to 100W and I & sup2; C. FB and optocoupler drive mode, adapt to all kinds of product applications, can repeatedly erase, online upgrade, PC online debugging, simple design After dismantling the 30W 1a1cusb PD fast charging charger made by Jingdong, it was found that the protocol chip used ip2726 Ob2362 of Ambro, NMOS and ru3040m of ruichips and ln5s03 of lishenmei are used as main control chips, rectifiers and rectifiers
