Slide Detect Circuit

How the Slide Detect Circuit Works

The Hall-Effect sensor circuit monitors the position of the slide mechanism to determine
if the mobile terminal is in open or closed position. The sensor has an open-collector
output that is driven to ground when a magnetic field of appropriate strength is present.
The sensor is located on the engine board and the corresponding magnet is mounted in
the slide mechanics.

Slide Detect Circuit Troubleshooting

When troubleshooting the slide detect circuit, make these common checks (see
Figure 34):
• Check components are OK
• Check power Supply VFLASH1
• Check output (ADC reading) to UEMEK (HEADINT2) is low when slide assembly is
closed
• If OK check UEMEK
Hint: Use the Phoenix keypad test to determine if UEMEK detects the Hall circuit.
