The allowed input voltage can reach 24V. It can output several fixed voltages from 3.0V to 5.0V. COMS technology ensures low voltage drop and low quiescent current. Although it is mainly designed as a fixed voltage regulator, variable voltage and current can also be obtained through peripheral components. Features: low power consumption; low voltage drop; low temperature coefficient; high input voltage (up to 24V); accurate output voltage: tolerance is ±3%; HT71XX-1 series 30mA voltage regulator chip HT7130-1 HOLTEK package TO92/SOT89; HT7133-1 HOLTEK package TO92/SOT89; HT7136-1 HOLTEK package TO92/SOT89; HT7144-1 HOLTEK package TO92/SOT89; HT7150-1 HOLTEK package TO92/SOT89; ==================================== HT75XX-1 series 100mA voltage regulator chip main models HT7530, HT7533, HT7536, HT7544, HT7550 The HT75XX-1 series is a three-port high current low voltage regulator using COMS technology. It can output 100mA current and allow input voltage up to 24V. It can output several stable voltages from 3.0V to 5.0V. COMS technology ensures its low voltage drop and low quiescent current. Although it is mainly used as a fixed voltage regulator, variable voltage and current can also be obtained through peripheral components. Features: low power consumption; low voltage drop; low temperature coefficient; high input voltage (up to 24V); high output current: 100mA (Pd≤250mW); accurate output voltage: tolerance 3%; HT75XX-1 series 100mA voltage regulator chip HT7530-1 HOLTEK package TO92/SOT89; HT7533-1 HOLTEK package TO92/SOT89; HT7536-1 HOLTEK package TO92/SOT89; HT7544-1 HOLTEK package TO92/SOT89; HT7550-1 HOLTEK package TO92/SOT89; ================================= Voltage detection reset chip HT70XX main models: HT7027, HT7033, HT7039, HT7044, HT7050 HT70XX series is a three-port low voltage detector using COMS technology. Each voltage detector in this series can detect a specific fixed voltage ranging from 2.2V to 7V. The detector consists of 4 parts: a high-precision, low-power standard voltage source, a comparator, a hysteresis circuit, and an output driver. COMS technology ensures low power consumption. Although the detector is mainly used as a fixed voltage detector, it can also detect user-specific threshold voltages when used with peripheral devices (NMOS open-drain models only). Features: low power consumption; low temperature coefficient; built-in high stable reference source; built-in hysteresis characteristics; voltage detection reset chip HT70XX: HT7027 HOLTEK package TO92/SOT89; HT7033 HOLTEK package TO92/SOT89; HT7039 HOLTEK package TO92/SOT89; HT7044 HOLTEK package TO92/SOT89; HT7050 HOLTEK package TO92/SOT89; ================================== HT1621B/HT1622 is a 128-dot matrix storage mapping multi-function LCD driver circuit. The S/W structural characteristics of HT1621 make it suitable for dot matrix LCD display, including LCD module and display subsystem, and HT1621 has power saving function. Working voltage: 2.4V～5.2V Internal 256KHz RC oscillator External 32KHz crystal or 256KHz frequency input 1/2 or 1/3 bias and 1/2, 1/3 or 1/4 duty cycle can be selected LCD display Internal time base frequency source Buzzer drive signal frequency can be selected from 2KHz or 4KHz With shutdown command to reduce power consumption Internal time base generator and WDT watchdog timer Internal time base or WDT overflow output Eight time base/WDT clock sources 32×4 LCD driver Internal 32×4bit display RAM Four serial interfaces Internal LCD drive frequency source Available instructions to control operation Data mode and command mode Instruction R/W address automatically accumulates Three data access modes VLCD pin is used to adjust LCD working voltage
