Foreword
♪ To each and every one ♪
Unmanned machine selection and over-balancing procurement with decision makers.
The drone market is reshaping the entire low-altitude economy at a visible rate. From consumer-class flights to industrial inspections, agricultural plant protection, logistics distribution, to military reconnaissance and emergency relief, the UAV operational boundary is updated every year. However, behind the flight is the almost stringent requirement for power units — battery protection circuits must respond to anomalies within milliseconds, power-driven MOSFET must remain extremely low in high frequency switches, and failure of equipment at any point may mean a crash.
For semiconductor procurement and decision makers, there is only one core proposition for the drone selection: to find the best solution for performance, reliability and cost within limited weight and space.
The MOT provides an in-depth and optimized MOSFET option for the two core applications of drones, which helps to create a differentiated advantage at the component level in the intense market competition of your product.
01
Scenario one: battery protection –
Secure the first door to flight safety.
The protection of circuits (BMS) by drone batteries is the starting point for the safety of the entire aircraft. The requirements for the protection of MOSFET from 1 to 2 sections of lithium power applications appear to be simple, but they are extremely precise: ultra-low-conductive electrical resistance control of thermal heat, rapid response protection overload, and small encapsulations with tight PCB design.
The following products have been recommended for the lithium-protected scene of 1-2 sections:
MOT8205A6, MOT8205SA6, MOT2060D, MOT2090D, MOT4406S
The entire product uses a unique device structure that achieves industry-led low Rds (on) in very small packagings, with little additional heat dispersion in on-board conditions, and high EAS avalanches with significantly better resistance to battery surge shocks than similar products. For the UAV complex that pursues extremely light-quantitative designs, this range of products can increase the reliability of battery protection circuits to new steps without increasing thermal area.
02
Scenario two: Three-by-one BLDC power drive –
Key variables determining flight performance
The push, response speed and continuation of drones are ultimately attributed to the efficiency of the power-driven system. In the three-phase straight current power (BLDC) drive circuits, MOSFET bears a constant switch stress under the high frequency PWM mode – low switch wear and tear, fast-body diode restoration, excellent flask polarity – which is the core criterion for the eligibility of a MOSFET.
MOT provides a complete product array for the 20V-80V phase 3 BLDC drive:
MOT2914J, MOT2265J, MOT80N03D, MOT90N03D, MOT3132G, MOT4160G, MOT4108HG, MOT4106HG, MOT6112HG, MOT6111G, MOT81117HG
Covers full current segment demand from the light consumption stage to the heavy load industrial stage. The low-pressure segment product (MOT2914J/MOT2265J) achieves very low-conductive general losses for small-axis light-range quantifying machines in applications below 20V; the medium-pressure segment product (MOT3132G/MOT4160G and above) is oriented towards the large-axis industrial drone and multi-wing heavy-loading platform, which maintains a stable switch shape and excellent heat performance within 80V.
Why Jin-ho?
Three key elements of procurement decision-making Dimensions
The supply chain is autonomous and stable. Against the backdrop of persistent global semiconductor capacity constraints, the supply stability of national production plants has become a core weighting indicator for procurement decisions.
2. With regard to parameter pairing, the cost structure is better, the MOSFET series of drones provides a comprehensive overview of the international mainstream brand products on key parameters such as Rds (on), Qg, and the time of reverse recovery of the cylindrical diodes, and the procurement costs and period flexibility have a significant advantage in helping clients to take initiative in BOM cost control.
3. Indigenous technical support, selection response rapid engineering teams can provide complete thermal simulation reports, joint programme recommendations and PCB layout guidance for specific aircraft types, run side by side from the NPI phase to the volume industry, and conduct large-scale compressor validation cycles.
Concluding remarks
Competition in the low-altitude economy ultimately contrasts the technological accumulation at the plant level with the resilience of the supply chain. The choice of a reliable MOSFET is responsible for the safety and efficiency of each mission.
Integrator electronics – with the strength of the national plant – provide a solid power base for each take-off from the drone industry.
