Solution introduction

At present, in the high-speed hair dryer market, the mainstream PCB solution is divided into A: full-bridge module + MCU; B: Half-bridge module + MCU: C: Discrete device + MCU encapsulated high-voltage drive; ESOP9's half-bridge power module TP1F series integrates 1 half-bridge high-voltage driver + 2 fast-recovery MOS: compared with scheme A, the PCB layout is more flexible, the heat dissipation is better, and the cost is lower; Compared with the C solution, there are fewer components, lower requirements for the main control package, better device consistency, higher PCB yield, and the cost can be equal

The solution adopts a domestic M0, with a main frequency of 60Mhz, built-in OP*2, CMP*2, 32KFlash, 4K Ram, GPIO*26, combined with Tale-Semi's hair dryer software solution and unique diode reverse bias MOS internal resistance sampling patented technology, which can greatly save the available GPIO of MCU and fully cover the peripheral function requirements in the field of high-speed hair dryer.

Thanks to the TP1F series' bottom-side cooling dual PAD, the power density output is greatly improved in a more compact area.

The picture shows that in TP1FM5004C, at 120W power, no air cooling, and 10 min, the thermal field performance is basically the same as that of TO252 package MOS under the same specification.

Advantages of the scheme

Support single/double resistor inductive FOC; Among them, single-resistor sampling is supplemented by diode reverse-bias MOS internal resistance sampling technology, which is consistent with the starting effect of dual resistance. supports zero-speed closed-loop and is compatible with IPD start-up;

Support high-speed operation;

It can support the key circuits of power-on self-test and improve product safety.

Support over-temperature, short-circuit, over-voltage, and under-voltage protection;

Support constant temperature control of heating wire;

Supports less electrolysis;

It supports motor temperature online identification technology, and the temperature field protection of the whole machine is safer and more reliable

No matter what the starting method, the starting success rate is 100%, and the algorithm has been verified by 10KK level shipment: the module comes with accurate VTS output, which can be used directly in parallel, with good consistency and reference

Retaining the hardware constant power control mode, the power of the air outlet is more stable.

Super compatibility,

Operating noise jitter suppression
