Toshiba has developed the SSM10N954L, a 12 V common-drain N-channel MOSFET specifically designed for battery protection circuits used in Lithium-ion (Li-ion) battery packs for mobile devices and other equipment. Li-ion battery packs require robust protection circuits to ensure safety during charging and discharging. These circuits need to minimize heat generation and offer high-density mounting options. Toshiba's MOSFETs with low on-resistance are designed to meet these requirements.
The SSM10N954L MOSFET builds upon the success of its predecessor, the SSM6N951L, by incorporating advanced micro processing technology to further reduce its on-resistance. This lower on-resistance enables the MOSFET to achieve low power loss, enhancing the overall efficiency of the battery protection circuit.
In addition to its low on-resistance, the SSM10N954L offers another noteworthy feature: low standby power consumption. This is achieved through the reduction of gate leakage current (low gate-source leakage current), allowing the MOSFET to operate with minimal power drain when in standby mode. As a result, the battery life of devices using the SSM10N954L is extended.
The SSM10N954L is packaged in the compact TCSPAC-153001 package, measuring approximately 1.49 mm x 2.98 mm with a thickness of 0.11 mm (typical). This small form factor facilitates high-density mounting and contributes to space-saving designs in battery-driven devices.
Overall, Toshiba's 12 V low on-resistance common-drain MOSFETs, such as the SSM10N954L, are tailored to meet the specific requirements of battery protection circuits in Li-ion battery packs. With their low power loss, high-density mounting capabilities, and low standby power consumption, these MOSFETs contribute to the efficient and extended operation of battery-driven devices while ensuring safety and reliability.
