AC Voltage Zero Cross Detection IC

BM1Z012FJ

General Description

Key Specifications

◼ VCC Input Power Supply Voltage Range:

-0.3 V to +29 V

◼ VH_AC1 and VH_AC2 Pins Operation Voltage:

600 V (Max)

This IC outputs the AC voltage zero cross timing detection

with high accuracy.

By eliminating the need for photocoupler and external

components required in conventional applications, it is

possible to reduce the number of parts drastically and

realize compact and highly reliable power supply

applications. In addition, this IC can reduce standby

power largely in comparison with an existing photocoupler

control.

◼ Circuit Current at Standby:

◼ Circuit Current at Operation:

◼ Operating Temperature Range:

50 µA (Typ)

160 µA (Typ)

-40 °C to +105 °C

Package

SOP-J7S

W (Typ) x D (Typ) x H (Max)

4.9 mm x 6.0 mm x 1.65 mm

Features

◼ AC Zero Cross Detection Function

Eliminates Photocoupler

Pitch (Typ):

1.27 mm

600 V High Voltage Monitor

Modifiable Zero Cross Delay Time

n Channel Open Drain Output

◼ VCC Under Voltage Locked Out (VCC UVLO)

Applications

◼ Household Appliances such as Rice Cooker and Dryer,

etc.
