Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] Due to the use of the motor drive circuit of the drive chip, the cost of the motor drive chip is high, and a larger motor power chip is required, and the cost of the entire system is relatively high; more vibration motor drive circuits occupy more panel space.

[0022] In order to solve the above technical problems, this embodiment provides a low-cost vibration motor multi-stage drive circuit, the circuit structure of which can be found in Figure 2-3...

Description

technical field [0001] The invention relates to the technical field of motor drive circuits, in particular to a low-cost vibration motor multi-stage drive circuit and a touch panel. Background technique [0002] At present, more and more car air-conditioning controllers use touch buttons to operate, so that the car air-conditioning controller can reflect a sense of modernity and technology, but it brings some problems. At present, many customers hope that the touch panel has vibration feedback requirements, but the current vibration feedback uses a special driver IC (DRV2605L-Q1), which is very expensive; [0003] works like figure 1 As shown, when the hand touches the touch button, the MCU (main control chip) detects the button signal, and then sends a signal to the driver chip of the vibration motor (DRV2605L-Q1), so that the driver chip drives the vibration motor to achieve touch feedback. Among them, the operating voltage of the driver chip is 5V, and a power chip (TLE...
